Well, I received one on Friday, installed it that evening, and originally had a few problems. Mainly with graphical issues in Counter Strike (its Half Life based for heaven's sake, which is based off of Quake II!!!!). Add to that it doesn't always apply FSAA/MSAA on older games (System Shock II, Counter Strike, a couple others that I have had time to test).
I loaded up Medal of Honor: Allied Assault, set the res to 1280x1024x32, with all graphics settings maxed, 4X FSAA, 16X AF, and it was one of the most amazing sites my eyes have seen. Not only did it look amazing, it ran butter smooth. I then loaded up Morrowind, same settings (sans shadows), and again, the output just amazed. It was significantly better looking than my GeForce 4 Ti 4600, and it ran much faster too.
Looking at ATI's past track record, they have done a very good job with this card's release. The original Radeon, then the 8500, all had significant problems at their release, so much so that many reviewers had a hard time recommending them. The Radeon 9700 has its share of problems, but for being an entirely new architecture, I think ATI has done a bang up job so far with it. Things will get better, but from all indications (well, my personal opinion here), about a month from now I think that many of the major problems that people have described will be gone. The driver dev. team seems to be working hard, and even though our friend Derek didn't have nice things to say about them, I think ATI is really moving in the right direction.
I can't wait to get the 9700 out of the test machine and into my main machine!
