Hardware.Info managed to snag not one, but three Nvidia GTX 480 cards and mashed them together (translated) in a 3-way SLI shootout against three ATI Radeon HD 5870 in triple-CrossFire. A dual-CrossFire 5970 was thrown in for good measure too.
For a large number of tests, even the dual-CrossFire 5970 configuration held its own, as well as the triple-CrossFire. As of this writing, GTX 480's are available in very low quantities and many gamers will find it difficult to snag one until Nvidia ramps up production.
After looking through the benchmarks, it's still very clear that the best bang for the buck title remains squarely in ATI's corner of the ring. While both ATI and Nvidia count on high yields to bring prices down, it's still unclear when consumers can see the results.
Hardware.Info ran its test with Intel's latest Core i7 980X 6-core processor. What they found was that ATI's triple-CrossFire scales far better than Nvidia's solution. According to the tests, adding a fourth GTX 480 will only give gamers roughly a 12.7% performance increase, which doesn't justify the cost as well as increased power consumption.
In fact, during load, the triple-CrossFire 5870 setup was running at 641 watts while the GTX 480 setup was consuming a whopping 937 watts--just shy of one kilowatt.
who is seriously in the right mind to do such a thing though? I mean, 3 GTX480s? Who needs so much power?
not to mention you need a small nuclear power plant to power that rig...
