100MHz FSB or 133MHz FSB what's the benefit with 133?

Hi!

As I'm planning to buy new parts for my computer I have a couple of questions:

1. Should I buy a CPU that's running at 100MHzFSB or a CPU that's running at 133MHzFSB? (Just Intel...)

2. If I overclock a CPU, lets say Intel 800MHz 100FSB with 133MHzFSB I get a speed of 1064 theoretically, is that better than a slightly o/c 1000MHz with 133MHz, or is it worse? No matter of the price...

3. Is it better with a CPU that has a higher multiplier than a CPU with a lower even if you get the same MHz with o/c.

BTW, I know that AMD is better...
The questions above is not regarded to the motherboard, of course it is very important what mobo I have but it maybe is possible to answer these questions without thinking of the mobo.

Thanks In Advance!

1. the 100MHz fsb cpu will o/c higher but at stock speed the 133MHz bus is faster.
2. The highert the bus speed, the beter the performance. a 1 gig p3 with 150MHz bus is faster than a 1.1 with a 100MHz bus.
3. Lower multiplier because you will need a higher bus speed to reach the same clock speed.

Keep in mind that you need very good memory to o/c your bus to over 140 MHz. at speeds between 100MHz and 133MHz your pci and agp buses will be runing out of spec. The same thing aplies to bus speeds over 133. make sure you have good components if you take your pci or agp buses very high.
