Your opinion on a good FSB choice

[Buuri]

My choices are 110x4 or 100x4,5 with my K6-3/450. I don't feel like doing playing around and benching them both, so I ask you what would you go with?
Me so lazy..

Also if anyone has managed to use FSB higher than 100 with that CPU and 4,5 divider on Asus P5A, let me know how.
FSB is not the problem but CPU doesn't seem to like to go higher than 450.

Thanks.

My opinion would be that memory running @ 110Mhz would be faster than the processor running an extra 10Mhz.. 4x110 = 440 with 110Mhz memory, or 4.5x100 = 450 with 100Mhz memory.. I may be wrong, but that's my opinion. Also PCI and AGP devices would get a slight boost in perf as long as they can handle it.

I agree w/ Guyver. I bet you probably spend more time waiting for instructions to fetch than you do waiting for a free CPU cycle. A faster bus would be good.

It might be worth a little more research though. Now that I think about it, Some SS7 motherboards that allow you to run at 110Mhz actually run slower than when they are set to 105Mhz. This is due to some extra added latencies, though.
Unfortunately, I don't remember what boards this is true for. I'd try 110 and 105. Also, maybe Joel remembers more about this than I do.
