My 8800 gts is the 320 mb model yes? How can I tell which model it is?
Whats a good upgrade for a 450 watt psu q6600 processor and 3 gigs of ram, which right now only show up as 2046.

Go for the GTS 450, it's an amazing card and has AMAZING overclocking headroom. I haven't found the ceiling on mine yet, and I've read that you can take it up to the 5770's stock performance. I'd recommend it as a great upgrade!
See I'm not too sure about that. Far as I can see, even just from the Tom's graphics hierarchy chart it's 6 tiers up, and 3 tiers up is considered to be a worthwhile upgrade. I went from a 9600 GT (which is better than a 8800 gts 320) to a GTS 450 and it was a MASSIVE improvement. Just my own personal findings and what I've read around, but I may be wrong!
I went from and 8800 GTS 320mb to a Radeon 4870 512mb to a MSI Cyclone GTX 460 1gb.
The jump from the 8800 to the 4870 was decent but from the 4870 to the 460 it wasn't as big of a difference. I have since upgraded my pc to a x58 i7 950. Back then I was using an E6600 overclocked to 3.2. I am currently using 2 460 1gb in SLI on my new rig.
450 watts it cutting it close for a 4870/gtx460. It should be plenty for a 450 though. For the money the 450 seems to be a great choice.
Both mosox and beekermartin are right. The 5770 is faster, but the gts 450 is still a very serious contender. You wouldn't lose with either of them to be honest. I'm biased towards the 450 because I have one, and after extensive testing last night I STILL haven't found its ceiling. As a card it just keeps getting better and better. In your situation I'd find prices on both, and if the 5770 is much more expensive than the 450 I'd go for the 450, you're not losing that much perfomance. But if they're the same or similar price, go for the 5770.
