with those specs how much of a difference is this going to make. for games like cod 4

Answer 1

You will get roughly double the number of frames per second. It will make the difference between unplayable and playable.

If you want to play around with some benchmarks, have a look here

look at the blue bars

Answer 2

I have both cards, and it is a massive difference.
When I ran 3dmark with the 6600gt it got like 8-10fps, but the 8600gt gets like 55fps.
The 6600gt could only do medium or low settings in the games I played and the 8600gt can max out almost everything, it runs FSX on high very well.
You will be pleased.

Answer 3

Hi. You will have to install it and see but in my experience there is no such thing as a GPU that is TOO fast.
