Would it be worth it to buy a new computer?

I have a HP Pavilion Slimline at 2.5GHz Dual-Core processor. It's using a Radeon 7750, a DVD RW CD RW optical drive, and a 286GB I think it is solid state hard drive. It's 2009 with an intel pentium processor and Windows 7 operating system. It has 3 USB 2.0 ports that are broken but with a 4 usb 2.0 port hub and 3GB of RAM. I would like to know if it would be worth it buying a new computer OR if it would be better buying an Intel i7 processor (3rd or 4th gen) and installing it manually. What are some problems I could face with installing one manually? I've seen processors that have Intel HD 4000 graphics in it already without a graphics card, would that interfere with my Radeon 7750? Could I fix that? Would it be worth buying a new gaming computer or would it be better buying an intel i7 processor at 3rd or 4th generation? If I were to buy a computer, I would buy one of the following:


Or something that is below $720 and is at least quad core i7 or at least hex core AMD. I would much prefer Intel i7 though. And I would need at least my Radeon 7750 or better. I only use Windows 7, not Windows 8 so if it comes with 8 I will install 7. If I buy an i7 processor and install it into my current computer, what processor would be compatible with my computer? LASTLY: I will pay no more than $350 for the i7 processor. Thanks for reading!

Ok here is the issue. To upgrade the processor to an i7 you would need a new motherboard. Which won't fit in your current system. Your current system doesn't use a standard motherboard so the new motherboard probably won't fit in the case.

Here is what i would do. Whether it's cheaper or not my preference is to build my own. You can carry over the HDD, RAM, and possibly the optical drive from the old system into the new. So you'll spend about $350 on the CPU, spend another $150 or more on the motherboard (maybe less), find a good deal on a cheap case (under $100), and spend about $100 on a good PSU and your set. Any money you have leftover can go into upgrading to 6 or more GB of RAM. If you need a new optical drive you can get a DVD-R/RW drive for about $40.

No the on board graphics on new CPUs can't even match your 7750. The on board graphics are not made for moderate to heavy gaming.
BTW i recommend a good 550W or larger PSU. Gives you a little head room for upgrading the GPU later. Once you have a good solid PSU, a decent case and drives you can continue to upgrade with those items for some time to come. Motherboards, CPUs, RAM, and Video cards will come and go. So it's good to have everything else on hand to keep your costs reasonable as you find the need to update your PC.
Thought i would put together a list of possibilities for you. This gives you a good mid range system with your current video card. I would suggest adding more RAM as well and you can get a good amount for about $100.
All that for less than $600 before cost of shipping. Leaving you plenty of room to add little odds and ends you may need. Or upgrade on of the items a bit further.

One last question, before I build my PC. How do I install two graphics cards on my computer (A radeon 7790 & a 7750), while my 7750 doesn't have a CrossfireX port but supports CrossfireX as plug and play?
Since the card doesn't have a crossfire port it can't support crossfire with the 7790. But you can still have both cards in the system, assuming your motherboard has 2 PCI-e 16x slots. This will allow you to run up to 4 monitors on your system.

So if I plug in both cards onto my mobo without a bridge, it won't work on one monitor? But I can use both for two monitors?
I'm not fully up to date on the current crossfire technology but my understanding is both cards need to have the crossfirex port for it to work. If you could get it working the better card would be throttled down to make it work. Then again they may have a way around that now. My limited knowledge tells if you want crossfire then get matching cards. But since your current card isn't capable of it then buy the best card you can and stick with that.

So if you use both cards each will have to have a monitor plugged into it otherwise the card won't be utilized.

Would I see much of s difference using an Intel i7 4th gen @ 3.5Ghz Quad core or using an AMD FX-8350 Vishera 4.0GHz Eight core? I don't see much of a difference between the two other than the processor speed. I still think the i7 is better, but if it's not much of a difference, it could save me like 120 dollars. Also, I found this package: http://www.newegg.com/Product/ComboBundleDetails.aspx?ItemList=Combo.1434640, it seems like a good deal because the package is less than what the processor costs xD. I don't think I need that much power though. Does Newegg participate in Black Friday or Internet Monday? It probably partakes in Christmas sales, but I want to get the best for my dollar.
Not only does the AMD have a higher clock speed (which doesn't really say much now days) it has twice as many cores. This is great if your using applications that can multi thread the work. But won't mean much for the games you want to play. The main factor for gaming is the video card. So as long as the CPUs can keep up your fine. And both CPUs can more than keep up with your card. If you buy the CPU and motherboard separate just make sure the motherboard is compatible with the CPU.

Yes Newwegg always has great deal for black Friday.

I will take your advice and will take the parts list under consideration. I went to my local computer shop and his employees will try to get a parts list of what I want however I said nothing of money so I hope they get a price of under $700 considering the price you gave me. They said they'll get me an Intel i7 4th Gen, 8-16GB RAM, a computer case (They have tons of computer cases that they'll probably just give me one even if I don't use them to make the computer), and I don't remember what motherboard they would put in the computer, however I just remember he said the capacitors are gold plated.
A local shop will be paying about as much for the parts as you would getting them direct from Newegg or other online distributor. So they need to add a 6% or higher markup to make any kind of profit.

Gold plated capacitors!? That doesn't mean a thing in regards to performance or quality of the motherboard. Gold plating does nothing to improve the performance or longevity of capacitors.

In addition to the problem of the MB not fitting the case you are also going to run into heat issues. Those little cases were not meant to run anymore than basic components. They don't have the capacity to add extra cooling so its going to overheat. Salvage and reuse what you can from the current one and get a case that allows you to configure things how you might need in the future. Cases are relatively cheap compared to other parts unless you go for a top of the line one which in my experience is often a waste of money. And often the power supplies that come with the cases are marginal so get one with no PS and buy a good power supply. Look at the product ratings on New Egg, they will give you a good idea of things to avoid.
OR build a new one over time as the components you want go on sale and keep the old one intact as a second or standby. 
I upgraded this spring, the basic parts are : MotherboardCPU  , RAM , and SSD  A 1 KW power supply and a GeForce GT 640 2GB 128-bit DDR3, a modest video card.  A lot of odds and ends like removable drive bays are nice to have but add up fast. Anyway, its all put together and runs very fast and stable but I still use my old one way more.  The new one works great for video and photo editing, stuff that takes a lot of horsepower, but all my software is on the old one and I have no problem with leaving it on all the time for convienence.  After a while , and if you can afford it, you find that having multiple computers for doing different things is pretty handy. I have an old one that is used mostly just for testing components and cleaning virsus.  I don't really care if it gets messed up, I have a back up of the software and the hardware is cheap.
I like AMD, they have been an good affordable alternative to Intel. The 8 core processor flys through everything.
Follow the sales, buy parts on sale, save a lot of cash and put it together as you can afford to.  I don't think I have ever had a computer that was "done" as I am allways changing things depending on what is available and what I need.  I went to using water cooling for a while. It was fun, I had both the CPU and video card with tubes running in and out. But then they changed the socket and my cooling system didn't fit anything anymore. The new one runs so cool I don't need any extra.
A good computer is always a work in process.  Usually the only reasons I upgrade is for the next generation of things, like USB 3 and SATA 3 and faster RAM.

About the processor you put in your system, would your AMD CPU match the i7? It seems it would because it is eight core at 4GHz though Intel i7 4th gen is 4 core at 3.5GHz though hyper threaded is 8 core.
You need to look up (Google) the advantages of each one. There are a lot of reviews about them and the strengths and weaknesses of each. I have found that the speed differences are so slight that nobody really notices. For most uses people don't need the absolute top of the line. If you have unlimited funds then great, but for normal peoples use price is the big consideration. For example, I recently got a USB pen drive for a kid who's school told them they needed them for computer classes. I got him a cheap 4 gig one that if he loses or it gets stolen its no big deal. He will likely not even use more than 500 meg of that for his school assignments. He said though that one of the other kids showed up with a 64 gig drive. What is the point of that? It just means when it gets stolen he is out lots more cash.
The AMD one can be overclocked. It is one of its selling points. They even provide the software for doing it. I probably will never have the need to push it that far. But the full 8 cores means it can do more things at the same time. Which is what I tend to do. Keep in mind also that now that AMD owns ATI the two play together very well. When ATI releases a new video driver you can bet that it was tested with every kind of AMD chip.
I have found that it is better to get a good motherboard and a less expensive processor and plan on upgrading the processor down the line when the prices fall. MSI has been one of my favorite boards but this Asus one had all the good features that I wanted and the price was right. I don't like Asus warranty work, they take forever, but I hope I won't need that for this setup.
Buy on sale, get the most for your money.

I've chosen a Newegg Package that I think will be good for what I want to do. (http://www.newegg.com/Product/ComboBundleDetails.aspx?ItemList=Combo.1413551). I also have another GPU (A radeon 7750) I have, so I understand that I can have dual GPUs. What SLI bridge can I use? (Not too experienced with setting up computers, :P)

Nevermind! I found one for $6 on amazon (http://www.amazon.com/gp/product/B004RIOFPM/ref=olp_product_details?ie=UTF8&me=&seller=)

It could save me $120 if it does match it's capabilities. What's the difference between the two?
Vyger3 years ago
So, here is the kind of deal I am talking about that you need to look for. NewEgg has 48 hour sale going on. The clock is counting down. They have a case listed by Rosewill that was 59.99. They are selling for $49.99. But there is a 10 rebate and  with this sale another 10 off for the sale. So you can get this case for $29.99 and free shipping. That is half price. From the looks of it and from the reviews its a good case, if you like red.
There are also power supplies on sale that fit it. So you need to shop around and find the deals. People will buy this case and then turn around and resell it on Ebay. Get it now for the sale price and you are already ahead.

By the way, the Asus mother board is on sale also and has a 20 rebate.

I would buy the MB but I'm a bit busy for a few weeks. Would this motherboard work (http://www.newegg.com/Product/Product.aspx?Item=N82E16813157384) with the i7 (http://www.newegg.com/Product/Product.aspx?Item=N82E16819116941)?
That motherboard has integrated video, why would you want that if you are trying to set up a gaming system?
Its also a micro board which means its smaller than a standard board and will not have as many features. It will also be more cramped for connecting everything.

a i7 won't fit your Mobo socket so you're stuck pretty much with just starting a new build, with some salvage, or buying a prebuilt rig. Either way there are somethings you are going to want to make sure of or watch for..
  • The CPU graphics will not cut it. From your other posts you want to do some gaming. Onboard is not the answer. Personally I'd just buy a matching 7750 and crossfire the two of them. I did this with a couple of old (5 years) 9600 GTs and they have yet to be conquered.
  • When you get a new mobo make sure it has PCI 3 compatibility. It won't be long before it's the standard and if you don't have it in a few years you will need to buy another mobo to upgrade any further.
  • Make sure the mobo has native USB 3.0 for the same reason you want PCI 3. You may not need it now but you'll regret not having it in a few years.
  • The newest standard for SATA is SATA 6. Not a huge deal but when running SSDs it could almost double your potential speeds.
  • Probably isn't an issue but check if your optical drive is IDE or SATA. My orginal build had an IDE drive and current gen mobos don't have IDE support.
