change ram. to a gskill ripjaws 6gb(2x3) its more cheaper. so you can save money. corsair is pricey bcuz of the DOMINATOR. and your video card is overkill for your reslution. get a 5850 instead and crossfire 2 5850 in the future.and change psu. to corsair 750wats. its more realliable. the others are ok.
