Its all up to you mate...
I myself have been with AMD since the K6 and don't see myself crossing over.
I'm very happy with my current rig, even if I can only get the 9850 stable to 2.8 ghz (hoping Asus gets a us a new bios soon). But even at that clock speed I have noticed that it still kicks butt on many chips that clock a lot higher.
Yes the main issue is the support that asus is giving to this board.
