if this is supposed to be a gaming rig, i would ditch the i7 2600k for an i5 2500k. as a gamer, you won't experience much benefit from the i7's hyperthreading and it'll cost you $100 more. i would reinvest that money in getting the best GPU possible. most games these days are bottlenecked by GPU and the way AMD and Nvidia are staggering releases the top-tier cards are actually a good investment. you can get a top-tier card now and sell it a year from now at 80-90% of its debut price to upgrade to the latest and greatest without much cash outlay.
if you want a sweet sub $1000 build, check mine out: www.rightrig.tumblr.com
tnx for the advice boss. But this rig is not for gaming, its mainly for rendering 3d and edtiting videos.
