kinda depends wut resolution u r gonna play at, i kinda recommend that u save a little and get a single gpu like 5870 even if u game pass the 1920x1080.

keep that money and get a next gen card current dx11 cards really dont do that much and all those eye candy games will come probably the same time when new gen gpu comes out.

rest is all good even my i5 with single 5870 plays mass effect 2 fine and thats still a dx9 base engine with some new effects.

1 is better than 2 raid for ssd, yes ur iops will double but u will lack trim. performance degrade will be worse in the end.

ppl get ssd for their fast seek time and raid wont improve on that, thread starter wants a gaming machine not a benching machine.
