X-bit Labs took a Gigabyte GA-X58A-UD9 Super-Mainboard and attached two different sets of GPUs for testing, four Radeon HD 5870s in one case and three GTX 480s in the second.  This board sports a pair of Nvidia NF200-SLI chips so there are plenty of PCIe lanes to go around and with the addition of a Xigmatek 1500W PSU to the installed Zalman 1000W PSU there is 2.5 kilowatts of power available for the system.  While the results in and of themselves are incredible, showing off the incredible graphical power available to those who can afford it there is another important factor to remember when looking at the results; while the difference between the AMD and nVIDIA scores are definitive you should pay careful attention to how much benefit you get from adding that fourth HD5870 or the third GTX480 to the system.

“We are going to test four Radeon HD 5870 graphics cards in CrossFireX configuration and compare them to a 3-way SLI configuration of three GeForce GTX 480 cards using the newest super-expensive mainboard with seven PCI Express slots onboard, four of which work in 16x mode.”
