Assassin's Creed (DirectX 10)

All settings for all cards were at maximum available for my setup. When you are on the rooftops and there is plenty on screen, the game experience is actually quite similar on all three cards, but when you climb a tower or find yourself in an alleyway and the visuals are restricted somewhat, then the 4890 begins to ramp up it's performance.

Crysis Warhead (DirectX 10)

Crysis Warhead punishes cards, and even this 4890 doesn't put out the greatest of numbers, but it's certainly very playable compared to the competition we have here. It's a pretty big jump in frame rates and it can make all the difference in game.
