The GT210 is a low end non-gaming GPU, but it should be able to handle COD7 without much problems. The only problem is that the game is badly coded. So you can expect stuttering.
FarCry 2 would run at low settings and lowered resolution. Crysis 2 as well. Same goes for BFBC2. There's no doubt it can run those games, but just not at high FPS rates.
I set my COD 6 ( Modern Warfare 2 ) 1024x768,AA2,all settings off except Ragdoll,Soften smoke edges and Shadow.
the texture settings i set it to AUTOMATIC. Awesome. Thanks Btw, reli appreciated it.
