Test System Setup, Benchmarks, And 3DMark
We are testing all of the cards against reference models to quantify the benefit of spending extra on these factory-overclocked offerings. We have a GeForce GTX 480 on hand, but are simulating a reference Radeon HD 5870 by using a PowerColor Radeon HD 5870 LCS, based on a Radeon HD 5870 PCB. We also swapped the PowerColor Radeon HD 5870 LCS’ water block with a reference Radeon HD 5870 cooler.
These cards are overkill for resolutions of 1680x1050 and below, so we'll stick with 1920x1080 and 2560x1600. We're making a conscious effort to supply relevant benchmark results here, so we won't opt for high levels of anti-aliasing (AA) unless the frame rates allow for it. Our goal is to get average frame rates close to 60 FPS and minimum frame rates above 30 frames per second.

3DMark is most useful when comparing Radeons to Radeons and GeForces to GeForces because the benchmark definitely favors certain drivers and architectures. This chart shows us some interesting info as far as how the overclocked cards compare to their reference models, but don't assume the performance in games will reflect the Radeon vs. GeForce results.
