Catalyst 8.3 and CrossFireX previewed
As you can see, 3DMark06?s performance improved by 55.9% with a second GPU installed. With a third-GPU in the system, performance increased by 67.8% over a single GPU. And with a fourth GPU added to the mix, performance went up by 71.4%.
Our custom Half Life 2: Episode 2 benchmark was set to tell a more impressive story before we ran into issues. Performance in this game went up by 82% moving from one GPU to two. Then increased by 152% with a third GPU, before stalling with a fourth. We should note, ATI?s internal benchmarks show additional scaling in this game with a fourth GPU, but we didn?t have any luck on our test machine.
