Performance in Simulators
Colin McRae: Dirt 2
The GeForce GTS 450 SLI tandem and the single GeForce GTX 470 are roughly equal to each other in this test. The latter is somewhat more expensive but easier to use and free from compatibility issues typical of SLI and CrossFire configurations.
Tom Clancy’s H.A.W.X.
The game’s integrated benchmark cannot report the bottom frame rate. We use DirectX 10 and 10.1 modes here.
We’ve got good results at 1600x900 but the GeForce GTS 450 SLI is only as good as the single GeForce GTX 470 and GeForce GTX 460 1GB at 1920x1080 and higher. So, this SLI tandem doesn't make much sense here as well as in most other tests.
Performance in Strategies
We use DirectX 11 mode for appropriate graphics cards.
The GeForce GTS 450 SLI has a much lower bottom speed than the GeForce GTX 470 and also loses to the latter in terms of average performance at resolutions above 1600x900.
StarCraft II: Wings of Liberty
It is in terms of bottom speed that the SLI tandem of two GeForce GTS 450s enjoys an advantage in StarCraft II. The tandem's average frame rate is quite impressive at the two lower resolutions, too. The 2560x1600 results spoil the triumph because the bottom speed is lower than the comfortable 25 fps, but we must admit that even the Radeon HD 5870 fails to reach the comfortable level in this game with FSAA turned on.
