What I like -- it looks nice, it works wonderfully
What I don't like -- It wouldn't let me use SLI for the first few months so I ended up selling my video cards and it was incompatible with a good bit of software I had.. But I think this has changed recently.. And remember going from NT to 95? That's what it's like going from XP or older to Vista, you have to learn things over again. It was quite frustrating for me at first and I considered reverting to XP, but now I'm more comfortable with it.
