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.Battlefield: Bad Company 2 is an all-new benchmark and 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.
Conjecturing somewhat, AMD already has the twin-GPU Radeon HD 5970 in its arsenal and that card should be a little quicker than the two Radeon HD 5850s, thanks to a Radeon HD 5870-like shader-count. But you never know...
The upcoming graphs will have the Radeon HD 5850 XF and GeForce GTX 480 in non-regular colours, making them easy to spot.
