... you meant crossfire right <veg>
A good 850 would probably suffice, a decent 1k otherwise

SLI 5870 FTW!!!! I say around 750 should be good, its not a GTX480 with ACTUAL SLI XD

I'd go no less than 750W, but the 5870s are surprisingly efficient and I wouldn't doubt a 650w (high quality) would run that setup just fine.

sorry to be a politically correct nazi here... BUT YOU CAN'T SLI 5870's!!! lol sorry. SLI is for Nvidia cards. for ATI cards its called Crossfire or CF for abbreviation.

I see this mistake too many times.

Sorry to be a grammar Nazi but you should have started your sentence with a capitol letter not a lower case one, I see this mistake quite a lot as well. [:mousemonkey]
