System Setup And Benchmarks
We tested on an LGA 1366-based machine sporting Intel's fastest Core i7 processor, the 975 Extreme, overclocked to 4 GHz. The idea here is that we wanted to eliminate CPU bottlenecks wherever possible, though you'll noticed these graphics cards are so fast that CPU-bound situations are unavoidable at times.
Also, the GeForce GTX 285s had to be run at 100% fan duty cycle in SLI mode, else they'd crash.
Finally, it's worth noting that the Radeon HD 5870 intermittently exhibited corruption in the first 3DMark Vantage test.
