Intel has revised steppings several times since the PIII first came out. The newer .18u Coppermine steppings run well over 1 GHz quite easily. If you are looking for a fast PIII at a bargain price, go for a Tualatin Celeron. The "Tualeron" is a 100 MHz FSB, 256K cache .13u CPU. Basically a PIII Tualatin with a Celeron name. Depending on if you are an overclocker or not, there are a couple of nice options. Currently, you can get it in a 1.2 GHz version, ~ $105 retail. Overclocking it on a 133 MHz FSB will get you to 1.6 GHz. 1.6 is a challenging overclock. The good news is in January, the 1.0A and 1.1A versions will be out. The lower multiplier will make these chips a better choice. The Tualatin CPUs will do ~ 1.5 GHz easily A 1.1 on a 133 FSB = 1463 MHz. A 1.0A @ 150 FSB = 1.5 GHz. This is the setup I like. The higher FSB will have better memory bandwidth. The 1.0A should be under $80.
