Difference between new imac video cards

[looklost]

I've searched and have not found a good answer to this question. I'm planning on buy a new imac, I'm planning on upgrading it to the 256mb card. I'm doing this because I will also install windows on it to play games.

I don't care that the 24" imac video card is possibly replaceable.

What is the performace differences between the ATI and NVIDIA video cards? Does one have a noticeable advantage, and because the NVIDIA is powering a 24" monitor with higher resolution will that have an effect on performance? Hope you guys can help, thanks.

It looks like the 7600 is a noticeable improvement over the X1600, which would lead me to believe that it will be a good bit better, even with the higher resolution.

Also, even though you don't normally want to run a display at less than native res, doing so isn't bad for games. So the 24" extra pixels need not carry a penalty in frames per second.
