My advice is to stay away from AMD/ATI video cards completely. The have always had buggy drivers and still do. Someone is sure to point out that Nvidia has had buggy drivers also and that's true but with Nvidia it's an exception to the rule and with AMD/ATI it's the rule rather than the exception. Their reviews always look good but you never hear reviewers talk about their chronic driver issues.
Posting comments like this requires proofs. As an owner of multiple Graphics cards from both Nvidia and ATI and have never had driver issues with either I believe your statement is false!
