Real time vst processing DAW Software

Real time vst processing

Hi,
I process my guitar in real time through my laptop ( Win xp and Audiomulch as a vst host).
This is dedicated to substitute what was a big rack of effects and mixers.
My audio path has the guitar as only source and I don't use any samples.
I loop in real time ( through Mobius).

My question is:
Are Vsts stressed more ( more cpu use) with this kind of use rather than when processing pre-recorded material like several tracks of a mix ?

Thanks

not directly, but latency being a factor, you have to use lower buffers for real time use -- so yes, you generally incur more cpu stress with real time use.

Yes,
this is what I was suspecting.
So it means that the most important thing to invest in it's processor speed.
Ram: more than 4 Gb should be pointless given I am not using samples.
Same should be for hard disk speed: 5400 rpm shouldn't limit real time processing.

Are these assumptions correct ?

thanks !
