Test system and software suite
So before we begin I'd like to tell you a little about the testing methodology. We will perform our tests within a baseline of single GPU and multi-GPU performance.
As such, for NVIDIA we'll test with a GeForce GTX 285 and GeForce GTX 295 (dual-GPUs). For NVIDIA we'll use the ForceWare 190.38 WHQL driver in both Windows Vista and Windows 7.
On ATI's side we test the ATI Radeon HD 4890 and obviously the still going strong Radeon HD 4870 X2 (dual-GPUs). For ATI we'll use Catalyst 9.7 in both operating systems as well.
To be 100% objective we test on the very same test PC with the very same settings.
Here is where we begin the benchmark portion of this article, but first let me show you our test system plus the software we used.
