Pentium 4 is faster. Yes, benchmarks say that amd processors have way better performance, but that is only on websites with amd enthusiasts, and on other sites (intel fans) pentium 4's are better. So in the long run they are the same. Plus the pentium 4 2.8ghz is cheaper, and with H/t technology you can't go wrong, but you should get the 2.4ghz because it can easily be overclocked to 3.0ghz (so can the 2.8ghz pentium 4).
