It's no longer worth buying a PC that doesn't have a processor clocked at 2GHz or more. Intel has just announced new versions of the Celeron (cheapo Pentium 4 chip) with speeds of 2.1GHz and 2.2GHz for less than $90. With the 2GHz Celeron now priced at $83 per chip, it's really not worth fitting anything slower. The top of the range Pentium 4 now stands at 3GHz and is on the way to 4GHz.
