Anyone with a 8800GTS and single core cpu?

My system specs

AMD64 3700 overclocked to 2.7ghz
ATI 1900XTX
2 gigs of ram
19inch monitor 1280x1024
535watt Enermax PSU

I'm curious to know if anyone has a 8800GTS in a single core system. I'm currently looking to upgrade, but dont really want to splash out on a Core2 system (cpu,ram and mobo) just yet. I mainly play BF2142 and looking for some more FPS.

Thanks for any input
