Using an analogy again, a single line reeeeaaaally fast magnetic railway won't do the job as well as a slower but 24 ways highway. Going fast isn't the only issue, it's doing a lot of the same at the same time reasonably fast that is.
Of course, but that is why we have processors with numerous cores, both in CPU's and GPU's. In my industrial electronic project to which I write all the music I use all software synths now, VST's, except for one hardware keyboard that I'll probably never part with (Yamaha AN1X which is also my controller). In one song we have I have about 24 VST synths loaded with several playing at a time throughout the song. In addition to that I have numerous VST effects running on many of those synth's mixer channels doing various things - FX, dynamics processing, EQ, etc and the CPU meter is just about at 50%.
If my machine can handle all that running at once there's no doubt in my mind it can handle a single, or even several, flawless guitar amp sims running at once.
Oh, and I run at 2.5ms latency. I have an Intel Core i7-920 (the early original i7 model).
