Grudge Match: Triple Nvidia GTX 480 SLI vs Triple ATi HD 5870 Crossfire (GameSpot 5/28/2010)

One powerful GPU is enough to render most games at ridiculous frame rates and insane resolutions. When you add two flagship GPUs to a system to make an SLI or Crossfire setup, it's the definition of excess. Triple SLI and Crossfire is (excuse us while we dip into our newspeak dictionary for a word) doubleplusexcess. Everything about three monster GPUs slapped into one system screams it. The frame rates are ridiculous, the power requirements are monumental, the heat is off the charts, and the cost--it falls under one of those "it's better not to ask" scenarios.

CyberPower sent over a system loaded to the hilt for us to check out in just such a configuration. The company had to build a machine capable of handling the immense loads that a triple GPU setup demands. Outside of heat, there were power, noise, and bottlenecking concerns. CyberPower used the sizeable Thermaltake Element V chassis, inside of which it installed one front-mounted 120mm fan for the drives, another in the back for the Asetek CPU water cooler, and a third wrapped around a ducting system that blows directly onto the video cards--an absolute necessity considering that one GeForce GTX 480 almost runs hot enough to boil water. On the side panel of the Thermaltake Element V sits a gigantic 230mm fan that blows directly onto the GPUs. An excellent cabling job keeps air flow unimpeded throughout the case. To make sure that the GPUs weren't bottlenecked by other hardware, CyberPower pushed the 3.33GHz flagship Intel Core i7 980X processor up to 4.2GHz and paired it with 6GB of 1600MHz Kingston HyperX DDR3 memory. On the storage side, there was a speedy 128GB Kingston SSD paired with a secondary 2TB drive for extra space. A massive 1,000-watt Corsair power supply feeds the rig with energy. Everything totals up to $4,500, which amounts to a princely sum but one heck of a machine....

Wow! Maybe I should cope with 3x GeForce GTX 480 instead of waiting for AMD/ATi 6000 series.

Oh, will read this and get back.

Edit: Well, can't say I'm surprised, and 2 is the most efficient combination it would appear. Other then that, as Celeras is saying. Metro is a crazy beast of a game, but so is JC2 it would appear. And I know JC2 is pretty harsh on my rig.

Do you really only get 64FPS in Metro with triple SLI 480s? Jesus... beast of a game.

there has to be a bottleneck existing then. because that is rediculous. possible driver hold back or just bad scaling for that game.

The way it scaled from one card to two, and then two to three makes it look as though it's almost CPU limited in Metro in triple configuration. If so good God what would it take to scale properly?
