Performance in Simulators

Colin McRae: Dirt 2

We enable the DirectX 11 mode for graphics cards that support it.

The performance of the Radeon HD 5000 series cards does not depend much on the platform: the Core i7-975 EE is only 11% ahead at best, which is too small to make any practical difference. Replacing a Radeon HD 5770 with a Radeon HD 5850 is going to be a better decision since the latter card delivers comfortable performance at 2560x1600 irrespective of the CPU and platform.

The Nvidia cards are more sensitive to the platform, especially the newer GF100-based products which need a top-end CPU to show their best. However, it is still better to buy a faster graphics card rather than a faster CPU especially as the G200-based models from Nvidia do not support the DirectX 11 capabilities which improve the visuals of this particular game greatly.

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.

Here, all of the graphics cards, except for the flagship models, deliver the same results irrespective of what platform they work on. The Radeon HD 5970 and the GeForce GTX 480 are really limited by the Core i5-750. The former performs 2-5% faster and the latter, 25-30% faster when the CPU is replaced with the Core i7-975 EE. On the other hand, these performance benefits are not as crucial as to justify the investment into the expensive CPU. Purchasing a faster graphics card will be a wise decision.
