3DMark2001SE, Comanche 4, X²
Despite its budget origins the SK8T800 does well in 3DMark2001SE. A breakdown of the game scores can be found here. Notice the impressive lobby scores. That's where the Athlon 64 does ever so well. The newest iteration of cards, NVIDIA's NV40 and ATI's R420, push default scores up to around 25,000 marks. I can still remember, quite vividly, the race up to 10,000.
A touch slower in Comanche 4. This seems to be a chipset and not board-specific issue.
And quite the reverse in X²- The Threat, which always runs better on VIA's K8T800 chipset.
