That's not a fair question. I belong to the school of thought that believe the PSU is the most important component in the machine; if the PSU isn't strong and stable, then nothing else is. If it were me, given the budget, I'd get this: Newegg.com - PC Power and Cooling Silencer Mk II PPCMK2S750 750W ATX12V v2.2 / EPS12V SLI Ready CrossFire Ready 80 PLUS SILVER Certified Active PFC Power Supply
Then I'd look for a better deal on a 5770, like this: Asus EAH5770CuCore/2DI/1G Radeon HD 5770 Video Card - 1GB GDDR5, PCI-Express 2.0, CrossFireX Ready, DVI, VGA, HDMI at TigerDirect.com.
However, not everyone thinks the same, and if you have your heart set on a particular card at $189.00, then this Corsair PSU is very good too: Newegg.com - CORSAIR CMPSU-650TX 650W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply
