Although I'm not digging the huge power consumption and other problems of the GTX400 series, it has to be said that the potential is indeed there. Nice article; also interesting to see the CrossFire versus SLI technology performance scalingNope, placed in 2-way SLI things certainly are looking good. The driver team did a magnificent job, all titles we used were running SLI straight out of the box , there was no tweaking needed, no manual profiling ... nothing. It's a testimony of the multi-GPU driver development that NVIDIA started years ago, and right now you reap the benefits of that fruit. 3-way SLI well .. it opens up a can of worms called bottlenecks. We really need next generation processors for that. So guys there you have it, nobody will discuss or argue that a setup like this is loud and power hungry in terms of energy, it however is the best of the best performance your money can buy you and surely the x-factor here is huge. We very much enjoyed playing around with the GeForce GTX 480 in SLI and especially 2-way SLI seems to be a smackdown homerun when we look at the sheer performance scaling. In most cases you'll see 1.7x to 1.9x perf increases, and that's just breathtaking.
