Of course this card is faster than the GF6800, but it seems that to really see the difference, one will have to use either specific benchmarks softwares, or really high resolutions. It as also possible that the CPU was also a limiting factor.
With this card, one can play Doom3 around 100FPSS at 1600x1200.
