Which is more important MHz or FSB?

Pushing my E6300 and can get stable at 3.2GHz

Should I stick with that on a 7x multiplier or drop to 6x and drive up the FSB to 2000+?

Obviously in the latter I will lose some MHz but will the gains in FSB be worth it.

Mostly for videoing editing and encoding it is used

MHz on the CPU clock makes the most difference... unless your running quad core you probably won't notice any real gains from increased FSB bandwidth.
 
It depends on the platform and programme used. A 480fsb is the sweet spot for P35 IIRC, but on X38 the really high speeds of DDR3 help a little. But performance is negligable either way.
 
I think during encoding on Adobe Premiere, only ~80% of the CPU is used.

So in that case is it possible to argue that the extra bandwidth a high FSB would provide would be of more benefit
 
On my last system, socket 754 my cpu maxed out at 2400 mhz no mater what combination of multiplier or fsb I used but I did find with the lower multiplier and high fsb I was getting about 15% higher bench marks. Not sure if its the same with the cd2's but every other cpu i've overclocked has been pretty much the same; Not sure though if thats more to do with other factors such as memory ect.
 
Mhz is purely the chip speed, whereas FSB is a lot more hardware. FSB carries the signals from the cpu to the northbridge or summat like that. Transfers and tick. been a long time since i did anything computer-sciency!

still confused lol
can u expain it in 'E' Terms' :) (E2180 .v. E6550) plz
 
FSB doesn't make a huge difference to performance. The 1333 FSB chips are only ~5% quicker than the 1066 FSB models, so if you are going to be overclocking quite a bit more with a lower multi, it will be better.
