Im leaning towards the 5850 to replace the 8800 GTX. Ive had a google search. It appears my Gigabyte GA P35 DS3R (version 1) can support a 5850. Has anyone here made a similar upgrade with the same mobo? Feedback of any kind appreciated.

Graphic cards of PCI-E x16 2.0 would work fine even in PCI-E x16 1.0 slot. What you should check is to make sure is that you CPU is fast enough to keep up with the 5850. A Q6600 overclock to 3.7GHz/stock speed Phenom II X4 965/i5 750/i7 920 would roughly be the speed of CPU needed to not bottleneck the stock speed 5850 too much.Im leaning towards the 5850 to replace the 8800 GTX.

Let me get this right? A stock i7 920, bottlenecks a 5850?
Seriously?
A 5850 is a good choice.
I have a q6600 at the moment which will clock to 3.2Ghz. It may go higher, but it has worked well with the games Ive thrown at it so far.
The mobo does have a PCIE 1.0 slot and it can cause problems with newer cards. However, my bios has been updated and I am hoping it will be ok. Otherwise I will look at a 4890 to be on the safe side.

I think you misunderstood what I meant...I was merely suggesting to reduce the chances of bottlenecking, those are the level of CPU speed targeted.
Not all the games are that well-optimised on using the extra cores, and in those cases they rely more on the raw power.
Take X3: Terran Conflict 1,680x1,050 for example:
Components: HD5870, Asus P6DT Deluxe, Corsair 1,600MHz 6GB
i7 920@stock speed 2.66GHz: min 40fps, avg 86fps
i7 [email protected]: min 58fps, avg 121fps
i7 930@stock speed 2.8GHz: min 43fps, avg 88fps
i7 [email protected]: min 63fps, avg 129fps
i7 980X@stock speed 3.33GHz: min 48fps, avg 103fps
i7 980X@ 4.4GHz: min 63fps, avg 130fps
7 980X@ 4.72GHz (water-cooled): min 68fps, avg 139fps
So simply put, while that most games would be GPU bottleneck, there ARE games which would be the case of CPU bottlenecking the GPU...even for a stock i7 920.

A friend of mine did exactly that upgrade with a core 2 duo @ 3.4GHz and still got a noticeable (i.e. without FRAPS) jump in FPS. That was on a 680i mobo which has PCIE 1.0
