Since you're on a budget, I'd definitely suggest an AMD solution. $1500 is no where near enough to get a high-performing P4 system (unless you skimp out a LOT on all the other stuff) which is just not worth it. The P4's newest revision, Northwood, seems to win many benchmarks, but ones that have favored the Athlon in the past still do. The thing that is to Intel's advantage (and probably the only thing in their advantage) is that with an Intel CPU, you can match it up with an Intel chipset, which, to my past experience, has provided less headache than any other third party chipset. All that may change when the nForce matures (knowing nVidia's excellent driver record), but for now, that's where I stand. Performance wise, the two aren't all that different, it's a matter of price vs stability/compatibility. Although in your case, the price may be more important as third party chipsets have improved significantly since the days of the Apollo 133A. There are still the occational problems, and when they happen it'll be a headache for sure, but that kind of thing occurs to maybe 1% if even of all the people who buy them.
