get a 6800GS they are the same as the 6800GT in alot of benchmarks and beat it in most situations also they overclock further and if u get one on the NV41 core u can unlok its vertex shaders and pixel pipelines, i just bought a 6800GS with 512mb Vram it owns up, i got 5500 on 3dmark with P4 3.0ghz and 512 mb ram, which is considered a good score for such a low spec system 😀
