gonna upgrade from a 8800gt to a Sapphire ATI Radeon HD 5770 Vapor-X 1024MB . i have a coolermaster igreen 600w psu with 38amps on the 12v rails. the only site i can find stating the required amps is guru3d and they say u need 40amps. but on other forums people are saying that is not the case it will require less. any body with a 5770 what does your psu have on the 12v rails * +

i seriously doubt these early games will usefully use DX11. but 
if im honest nvidia are the ones who really push API's. the way its meant to be played. Pc gaming does owe a lot to nvidia for that program, and as i predicted a while ago physx was going to be pushed hard, after years of it languishing in a handful of games. nvidia have tonnes in the pipeline * +
