First off, I’d like to make it clear that we chose to limit testing to Windows XP and DirectX 9. The amount of folks with both Vista and a DirectX 10 card out there is still relatively miniscule at this time, and we’ll cover the DirectX 10 angle in the future when there’s a little more meat on the subject - specifically, when Crysis is released.
The Sapphire and Powercolor flavors of the 2600 XT have identical clock speeds and any performance differences were within the margin of error in our testing. To eliminate redundancy and make the graphs easy to read, we only published one set of results for the 2600 XT.
The test system is running an e4300 processor, with a very mild overclock to 2.25 GHz to simulate processors a little higher on the food chain.
