I'm trying to select a new system? I can't go over $1500. What would be my best set up? I'm will be getting a ATI 9800 Pro for sure. What's the best cpu do get right now for AMD. Should I get the 2500 Barton and oc it or should I get a 2800 or higher. And what would be the best memory and amount. I've never oc'ed before. Is it dangerous and how much cooling do I need. The system comes with stock cooling. I want this system to last.
