Performance in Simulators
Race Driver: GRID
Both GeForce GTS 250 models perform almost equally and compete successfully against Radeon HD 4850. However, when we overclocked our Palit GeForce GTS 250 1GB, we managed to get a significant average performance boost of 16-18%, which brings this card to the level of a more expensive GeForce GTX 260 Core 216.

This is another case when there is very tiny performance difference between two almost identical graphics accelerators that differ only by the amount of video memory. However, do not forget that Palit GeForce GTS 250 1GB has its memory working at a lower frequency, which may have lowered its chances of a more convincing victory. Although, I doubt that it could help Palit card to catch up with Radeon HD 4850, because the game evidently favours ATI Radeon HD architecture.
