some thing wrong..

Is getting 37-40 fps with a 8800GT normal in bf2142? In BF2 I get a 60 fps online and off but I get a horrible fps loss in BF2142. Is this expected with the amount of things going on? The rest of my system is C2D6600 2.4 ghz, 2 gigs of ram and a 750 watt psu.

I've got the latest drivers too, I'm just so frustrated with this performance, and I'm not even running on a high res either. Any one know anything that can be causing this?

What resolution and setting you running it at? Also are you using vista, that may reduce performance.

And isnt 40fps enough?

Are there any other games that show this kind of unwarranted lose in performance? if so its highly likely to be a driver related issue.

If you still have the driver version that you used when you had the 7900 try rolling back to it and seeing if it exhibits the same loss on the 8800.
