OK I admit personally I don't play guitar but have done some recordings for people in the past.

I can generally agree that with a reasonably modest computer (doesn't have to be the fastest in the world) and a half decent soundcard, just using one or two not-too-intensive effects you can usually get away with monitoring through the effected chain of the PC. If you are going to do this I would suggest using a more simple chain to give the idea of the sound you are after, record the dry (or both) signal(s) and then you have the option of applying more CPU/latency intensive plugins once it is recorded, yet you can monitor with at least an idea of what it will sound like, rather than monitoring dry.

I also have to admit so far I haven't played much with the effects available on Linux. Still trying to get myself migrated from Windows but little niggles often pull me back to the dark side...
