Spiff, the GeForce's major advantage is the SLI technology where you could link two cards together to run at the same time. From the specs I have seen at Tom's Hardware, the results are impressive. The Radeons have been slow to adapt this technology and their version is quite dissapointing from what I read. You can buy a $179 GeForce 6800 now and upgrade with another GeForce 6800 down the road (at which time the card will definately be less than $179) instead of buying the new $250 card and get almost the same performance.
It's too bad Roger won't budge on the AMD thing. I have been using AMDs for 6 years now and I never look back.
