Thanks XGUNTHERC I'll give them a go... I have tried pretty much all latest NVIDIA drivers including the original i had but nothing gives me the benchmarks I was getting using Vista and I am not a fan of Vista at all.

Also try to uninstall drivers from windows update ( if you installed them),I had similar issue, and that worked for me.

I just discovered something. I kept my benchmarks from "Furmark" from my Vista config and it shows clearly .. 2 g.p.u.'s operating. Since using windows 7 my benchmarks have decreased significantly and as you can see it states only 1 G.P.U. I was monitoring with EVGA precision and definitely only one GPU core was in operation. Any ideas as to why would be appreciated

Your benchmark software doesn't recognize OS like Win 7, but like Win server 2007 (bottom of the picture), maybe problem lies in incompatibility of benchmark software with Win 7...
