S.T.A.L.K.E.R: Clear Sky:

S.T.A.L.K.E.R: Clear Sky is another game that takes advantage of the capabilities of DirectX 10.1, and it also happens to have a free downloadable benchmark.  Set in the time period before Shadows of Chernobyl, the player assumes the role of a mercenary in a radioactive wasteland.  Based on the X-Ray 1.5 engine, Clear Sky makes for a popular benchmark. 

For the both cards, testing was again done at 1680x1050, with all other settings maxed out, including DX10.1 rendering and 4xMSAA.

The 4890 XXX put the pain on in STALKER, too, racking up gains of 24.5%, 36.2%, 23.3% and 23.9%.  Again, these margins are much higher than the stock versions of these cards.
