Geforce 8800 GTX vs 8800 GTS in 12 game tests
 

With standard rendering, the performances of the GeForce 8 surprised us even if they were announced to be limited by the CPU. On average, the GeForce 8800 GTX is 70% faster than the GeForce 7900 GTX! It is also faster than any of the previous multi-card systems. Clearly, the GeForce 8800 GTX doesn´t have any direct competitor. The GeForce 8800 GTS is much slower than the GTX version, whose deactivated units and lower frequencies of course explain this position, but still provides interesting results.

Why would anybody wanna buy 2x 8800GTS when one 8800GTX is cheaper and fast/faster?

2x8800GTS= €800+
1x8800GTX= €625
