New Computer Time

Well, it's time to get a new computer. The one I currently have is almost 5 years old, and can't handle the programs that I need it to regularly. I have been looking at changing to an AMD processor vs. the Intel. I like the AMD 64, but the ones that I can afford are not as good as the Pentium 4. Decisions, decisions...

Let me know what you use...do you prefer one over the other?
