I am currently saving up to upgrade my computer's GPU. I play Call of Duty 4, and I am only looking to achieve 125 FPS Constant as 1280x1024, even if the game doesn't look all pretty. I am not sure what the most ideal upgrade would be for this setup:
Even with a beast of a GPU that could approach constant 125 fps, you will probably then be CPU limited. You'll have to reduce details never mind fsaa. What's your refresh rate? 19" LCD you probably will only see 60 fps. Think you'll still feel 125 fps in multiplayer?
The reason I am looking to get 125 FPS is because I am a competitive gamer, and I want the game to run as smooth as possible, as much as possible. I have only one last question: Would a 8800GS or a 9600GT give me FPS no lower than 60-70 at all times?
