I've been thinking about getting a new Graphics card, I currently have a Geforce 7600GS.

Which of these is the best for Price/performance and so on?
Radeon X1950 Pro ($130, My friend has one, and its a lot faster than my 7600GS. )
Radeon HD2900 Pro ($260-ish)
Geforce 8800GTS 320mb ($280-ish)

Or should I wait for the Geforce 8700 coming in November? And the Radeon RV670?

i have not seen enough reveiws of the pro to fully answer that question, i only know of one and that is tweaktown. if you are in no hurry to buy then wait, if not, wait for more reviews to come out

What is your PSU?
Power Requirements could play a factor.

I'll probably wait until it gets closer to the Crysis release date.

I was just planning on getting a new one. My current PSU came with my case.

both the 2900 and the 8800 own the 1950, don't even bother. It depends on the benchmark who wins between the remaining two.

Take at look at this review! http://www.tweaktown.com/reviews/1 [...] index.html The 2900 Pro beats the 8800GTS 320MB in most tests and is cheaper.

Its really going to matter what the rest of your pc is like in pure performance terms the 2900 pro is getting good customer feedback and the one review we have seen says its quicker than the GTS at stock but it should have at least a little overclocking in it as it is basically a failled XT which could mean it was unstable at XT speeds or just not quite reach them,so the oc is not a gimme.Both are DX10 cards and while the 1950 is DX9 you wont do better bang for the buck.
Also remenber you need Vista to get DX10.
