Ooh, Ooh! A question I can answer with actual experience. I have both - a Sapphire 9500Pro and a BFG Ti4600. I've used them both in my machine and both are excellent. My impressions are mostly based on playing UT2003 because it has the best graphics out right now. I liked the Radeon best for its AA and AF - looks great and plays great. Same with the Ti4600, but it didn't perform as well with the good stuff turned on. Both cards are more than capable of playing anything out there (I've played Morrowind, Neverwinter Nights, UT2003, etc.) but I think the Radeon edges the Ti4600 - 9500Pro's in my machine, Ti4600's in my wife's! Oh, yeah, and with a little work, the Radeon overclocks better...
