I actually found a review on the ASRock mobo, I posted about earlier, in a computer magazine and according to that the performance is as good as a nForce4 based mobo has. Only bad thing about it was that there were some problems with the Athlon 64 4000+ and it didn't start up every time. I was encouraged by the article but then I started thinking about just saving up the money, getting a new guitar now and updating the complete system when Vista comes out and get a DX10 GPU and some nice AM2 system. Probably AM2.
