I have an x800 Pro that is getting sent back to outpost on monday - it is buggy and I get lots of solid green/yellow trees, boats, etc in farcry. I have pre ordered both an 800xt and a 6800GT. I think even tho they are within $20 of each other, I am going to go with the GT because I think once all the driver issues are figured out it will be able to beat/match the x800XT
I plan to watercool my setup and OC the hell out of the GT in late July. I also want to take advantage of the encoding paths and S3.0, and my experience with the 800Pro has turned me off of ATI a little bit.
Not only that, but the BFG has a lifetime warranty and I am running an nforce3 board, which i think may help the GT out a little
