I find that hard to believe, I got 15 fps on Bully with my old P4, it was only a:
Compaq Evo D510C with:
2.53 GHz Northwood P4
512 MB RAM
Inno3D GeForce FX 5500 (256 MB) @ stock
I never tried playing FFX, but I think I would have got 20 fps or more with it. Speaking of games, check your game against the compatibility list on the website, if its rated as 'Intro' or 'menus', then no PC in the world can help with that! Also, check your configuration and make sure it is correct.
