MSI R7970 Lightning Review: AMD's HD 7970 Gets the Treatment
Results: DiRT 3
Codemasters has probably the best looking racing games on the planet. They pulled out all stops with DiRT 3. This particular title features plenty of DX11 effects and tessellation (though I think they took a step back with water effects as compared to DiRT 2). The game used the Ultra preset with 4X AA and 16X AF enabled. The built in Aspen benchmark is used.
DiRT 3 is another title that is pretty CPU dependent. This is also a game that is more NVIDIA friendly than the previous iteration, DiRT 2. The R7970 takes the lead in every test, but the differences are not as big as we have seen in previous tests. Even the R6970 is not all that far behind.
