I want to build a gaming and video editing computer but my budget is limited to 500 dollars. I want to build an i7 rig because i7 is pretty cheap at microcenter for 199. Now i need a mother board that overclocks well and some ddr3 ram. Thats pretty much all i can get for 500 and then i plan to use the psu hard drive from my old computer and the graphics as well ill up these later. Need a crossfire mother board though. Also if you guys can get me complete set up for 500 that would be even better but something that overclocks i have been reading alot about it and want to try overclocking.
