Pooling the hardware from our previous GeForce GTX 295 quad-SLI comparison allows curious readers to compare today’s results to those of more elaborate, multi-card configurations. Highlights of our system include an Intel Core i7 920 processor overclocked to 4.00 GHz, a Swiftech Apogee-GTZ based liquid cooling kit for overclocking stability, and 6 GB of Crucial DDR3-1600 at moderately-tight CAS 8 timings.

Overclocking would be nice to see what the hardware can really do; but I generally don't dabble into overclock video cards. Never seems to work out, either the card is already running hot or the slightest increase in frequency produces artifacts.
Also driver updates seem to wreak havoc with oc settings.
I have not overclocked the GTX 285 yet, I am waiting for NiBiToR v4.9 to be released so once I overclock it, I can set it permantly to the final stable clock. I am expecting to be able to hit about 730 GPU, but it could be less.
In other words, no matter how well ATI's strategy of using two smaller, cheaper GPUs in tandem instead of one huge GPU works, you will still be able to say that Nvidia is the best.
Also, why would most people who are spending $400-$450 on video cards not want a dual-card setup. Most people I know see it as a kind of bragging right, just like water-cooling your rig.
One last thing, why is it so hard to find reviews of the 4850x2?
