GeForce Go 7700 Game Requirement Analysis
GeForce Go 7700 is a middle-class level GPU and a tweaked GeForce Go 7600. It can use up to 512MB of dedicated video memory, and it's available with DDR/DDR2 or DDR3 memory types.
The performance depends A LOT on the memory type it features. Games like F.E.A.R (from 2005) might run on the highest settings (DDR3) or might be only playable in the lowest settings (DDR).
All in all, the most powerful version is still not good enough to play any of today's current games.
