Well, no two games are the same.
Some games are heavy on the CPU others on the GFX card.
Elder games probably run just fine on your machine but many newer games uses shaders intensively, which is something your GFX card doesn't handle very well.
The FX5200 was a bad card even when it was released. The performance didn't match the cards of the previous generation.

That simply isn't possible. I doubt even the fastest consumer CPU's are fast enough to keep up with the GFX side of H2V.
If you wan't a performance boost, get a newer GFX card.
