As with the previous page where we tested the NVIDIA SLI scaling between the chipsets, we want to do the same for the AMD CrossfireX. When we decided to run this series of tests, we were able to get in touch with our friends over at XFX and they kindly sent over a pair of XFX Radeon HD 6950’s.
The ASRock Fatal1ty Professional takes the top spots in the charts with a single XFX Radeon HD 6950. Tossing in our second XFX Radeon HD 6950 the Fatal1ty Professional dropped to the second spot at 1280×1024, though it held strong in the top spot at 1920×1080!
