How do I get dual GPUs? Answered

Thanks to the people who answered all of my previous tech questions, that includes the Instructables pros like Vyger, bwrussell, AndyGadget, and mpilchfamily. So I've bought a computer package for $690 and it came with everything needed on a computer, optical drive, hdd, mobo, case, cpu, psu, radeon 7790, and I just had to buy ram. I bought it from Newegg. So here is my new problem: I am awaiting for the arrival of my computer parts, and I realized m Radeon 7750 does not have a CrossfireX port thing to put the bridge on. However, the GPU that came with the package does. I know that my Radeon 7750 does have CrossfireX support and after a Google I know that if I had dual Radeon 7750s that it would be a plug and play. My question is, can I run both graphics cards on my motherboard without a crossfire bridge?, because my 7750 does not have a port to put the bridge on.

Radeon 7750: I don't have a link, but it takes up one slot on the back of my computer and is able to fit into a Pavilion Slimline and supports CrossfireX (1GB).

The other computer parts I don't think are needed to explain.

Thanks for reading!

I believe you need matching (same model) cards. I have a pair of radeons in my rig, but they are the same.

I am not sure why your 7750 does not have the crossfire bridge port on it. You will need to look it up on the manufacturer's web site.
