TweakTown found 3DMark Vantage benchmark scores of two GeForce GTX 295 graphics card on a Core i7 965 EE system.
Both cards were first overclocked to 705/1400/2500MHz on the GPU, shaders and memory. The CPU was also bumped up to 4190MHz. The result is what you see above; P32573.
Sure, it doesn't beat any records (the top score is still held by a triple GTX 280 setup scoring 36598), but it's still a very impressive result and there's no doubt the drivers need a lot more optimizing yet.
