Crysis on medium with good fps? I really doubt it but you should be able to play GTA IV on low.
No, you will need to up your graphics and CPU.
You've got low ram, bad CPU and i doubt your graphics card can handle low settings.
Graphics? Judging by your CPU i doubt the graphics card would be any better.
it says up to 384mb graphic memory....will it work? At least on the lowest resolution?????
