Hi there. I just upgraded from an X800 Pro to the 7800 GT from BFG. On WOW I was able to run with the settings maxed and AA/AF at 1280x1024 even with my X800 Pro. I upgraded so I could play F.E.A.R. and will have to say I am very impressed so far. I also have some GeForce 4s and an FX5700 all from PNY that were total crap and 3 of them failed completely and the FX needed a new fan on it. The BFG 7800 seems like a quality product and I think nVidia has gotten their act together. The drivers only use about 2 Meg. of RAM vs the behemoths ATI has with that new Control Console. I picked up my 7800 for $299 on sale at a local store. In 3DMark05 the numbers are roughly:

9800 Pro=2200
X800 Pro=4900
7800 GT =7000

From what I have seen and heard the GTX will get you a score of about 7800. Not worth the money in my opinion especially if your going to get another for SLI.
