Low FPS for CoD: MW2

[keagster92]

I was wondering why i have low frames in this game, but most other games seem to be fine.. I use a q9650 3Ghz Quad-Core. 3GB Ram. Sapphire ATI Radeon 5850 1GB.. OS - Windows XP..
All of my drivers are up to date, it's just weird to me that i can't play MW2 with tearing on most maps. My recent card was a 9800GT 1GB and that ran the game very smoothly and no problems.. If anyone can give me some information on what the problem might be, please let met know, thanks..

3GB RAM? how many DIMMs?

Screen tearing? Turn on Vsync (also listed as Sync Every Frame) that might help
