Notes
Benchmarks were conducted at 1,680x1,050, 1,920x1,200, and 2,560x1,600, where applicable, with decent degrees of image quality.We've tested with the very latest drivers available from both companies.
DiRT 2 has also been updated to v1.1 since the last slew of tests. The patch appears to provide better performance for NVIDIA GPUs.
We'd have loved to include a GeForce GTX 470 in our performance section, but NVIDIA couldn't get us a sample with sufficient time to test. We'll be looking at the GPU in an individual review next week.
