Lots of benchmarks show the Celeron 2.2 overclocked to well over 3GHz losing to a Duron 1.2GHz in most things, which should scale to about what you have been seeing. The Pentium 4 is the same way (just not as bad). The best bet would be to get a 2800+ Athlon XP chip (if you don't want to overclock) as its the fastest MHz wise (2250MHz) of any of the Athlons for chess, and faster than any of the P4s out today for chess as well. If you'd prefer lots of speed and some overclocking, try one of my 2.4-2.5GHz Athlon XP pretested chips.. They'll put you up near P4-4GHz speed chess-wise and blow a P4-3.2 out of the water at everything else. I've already done the tests vs a P4-2.53 @ 3.32GHz in multiple applications (divx, mp3 encoding, compiling, encryption/decryption, sciencemark, chess, etc), the P4-3.32 lost by a significant ammount in most of the tests. Plus, at $79 for the 2.4GHz Athlon XP (3200-3400+ IMO) isn't bad at all.. Here are some chess benchmarks: http://www.newageoc.com/crafty/bench.html Note: I don't have any freon-cooled Athlon systems tested yet (at 3.4GHz), so that would beat the P4-4GHz w/ HT by quite a bit. The top Athlon on there is the 2.5GHz and that is AIR cooled. The top P4 is FREON (-50 celsius) cooled. You can see from here the 2.2GHz Athlon (Athlon XP 2800+ is 50MHz faster) beats a P4-3.25GHz. Celeron 1GHz (p3 core) is faster than a Pentium 4 1.5GHz, and an Athlon XP 1.86GHz (about like a 2200+) is almost equal to a P4-3GHz. Even the Pentium 3 1.12GHz beats a P4-1.6GHz. Good job Intel. :) Intel has it pretty sweet, though. Only company I know that can produce a product sigificantly worse than the last one and charge people 4-5 times more and have people actually buy it. My recommendation is take it back and build an Nforce2 based Athlon XP 2800+ system. If you'd like to save a little money and get some extra speed, head over to www.newageoc.com. If you don't know how to overclock I can manually 'lock' the chip at 2.4GHz that way you don't need to do anything but drop in the chip and put on the heatsink. :)
