Yeah, and in the end my pc is much faster in all aspects than your is...even though you have a higher Vantage score. This is why I called your result inflated...your E8400@ 3ghz, or my QX9650@ 4ghz...your two gpus VS my 4...
And when it comes to games with Phys-X, the only thing that yours might be faster in...you'd still be slower because you'd be using gpu resources for Phys-X, and on my system all gpu resources are available for graphics...Phys-X would run on my PPU...unlike yours.
So, in the end, the problem is that even though you got a higher score, your system is in no way faster than mine in any application, and as such, Vantage has become a "broken" benchmark, incapable of providing the measurement you are looking for.
