[COLOR=royalblue]ATI was running in their DX9 codepath and the mixed mode codepath was used for NVIDIA. No AA/AF was enabled and we're looking at 1024x768 scores.[/COLOR] IMO this scenario should work quite better for NVIDIA since GeForce boards perform worse with AA and anisotropic settings enabled.
On a semi-related note, The Inq guys noticed some sort of easter egg going on at Anand's recent videocard round up. Under test bed configuration they vaguely quote a "2.8GHz Intel Processor", however if you highlight that line with your mouse you will see the word "Prescott" hidden on the white background.
