The 7770 VGA is capable playing games in respected resolutions and settings, not the highest settings but really worth it's money. It's a cost effective card, round about $100, not many can beat that!
Replaced my Nvidia 8800 GTS 512 with 7770 now.
In euro the 8800 GTS 512 costed me about 225 euro. The 7770 was about euro100 and it's much faster.
Well worth the money!
