The only thing you need to look at is the psu.
My system is a:
Phenom II X6 1090T at 3.5GHz
ASUS M4A79XTD EVO AM3 790X
G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 1600
Antec EarthWatts EA650 650W
XFX HD-577X-ZNFC Radeon HD 5770 1GB in Crossfire

You should be ok with either card

I can handle GTX 470s in SLI on my Antec Earthwatts 650W. You should be good.
