I'm trying to build a computer for myself within the next month or so. I will mostly be using the computer for online games like wow and ff. As I said in the title I'd like to keep its under 700 I already have a moniter speakers keyboard and mouse. I also like to order from newegg they seem to have fair prices. Thanks in advance for all the help.
That means when two card are in crossfire (running two graphics cards at the same time) they will use pci-e 8x speed, instead of one at 16x speed and one at 4x speed. The 8x speed is plenty, you wont see a bottle neck there, however the 4x speed will bottleneck.
