Wiring your LED

So I just built a new garage and I want to make my own LED lighting for my work bench. I was looking at 1 watt luxeon leds and I was wondering if I need a resistor with those leds? I was looking on ebay and it said that the driver is already installed? I will run these with a PC power supply rated @ 800 watts will this work? Can anyone guide me thru this? Ive been looking on here and reading as much as I can... Thank you.
