would it be better to get a 100mhz FSB cpu or 133mhz?

[Wah]

does it make a difference?

It depends on what you want to do.

If you want to overclock, the 100 mhz would be a better choice

Example: You have a 100 MHz FSB P3-700e and a 133 MHz FSB P3-733.

The 700e has a muliplier of 7x, and the 733 a multiplier of 5.5x. Lets say you stick the 700e in a mobo that can overclock to 133 MHz. For every 1 MHz you overclock, you get 7 MHz more to your CPU. For the 733, you only get 5.5 more MHz.

Also, the 133 MHz FSB doens't have a lot of headroom, given that most PC133 SDRAMs won't oppperate reliably over 150 MHz. Thus you can only get ~93.5b MHz more out of a 733 (assuming an OC to 150MHz). On the other hand, you can get the 700e to reliably opperate on a 133 MHz FSB with standard PC133 SDRAMs (I think this equates to a total core speed of 933 MHz or so).

the 100 MHz FSB gives more core speed and slightly less FSB. The 133 MHz FSB gives more FSB speed and less core. I'm not entirely sure which is faster, and if the difference is noticable.

If you dont care about OCing your chip, go with the 133 MHz FSB.

Well you could pay less and get the 100 MHz processor and overclock it to 133 MHz. However, if you don't want to overclock get the 133 MHz chip.

The difference between 100 and 133 MHz CPU's isnt really evry big, so unless you really really dont wanna OC, go with the 100 MHz'er.
