Still got all the synths, actually I sampled some stuff from the SN2r last week, to be used as samples in Halion.. may sound odd, but consider this: SN2r: 24 voices and the hastle of having to wire it up, A/D sampling noise, etc. And now in the form of samples: 256 voices (or something :P) ability to run it through every DSP I want, saved with the song project, and even able to introduce sampler-artifacts such as pitching samples (which can sometimes be practical). Also consider this: an 8-part voice on the SN2r takes 1 voices, on a polyphony of 24 that equals 3 voices to play with. A sampled version doesn't have this issue anymore.
Furthermore: hardware FM synths are 100% obsolete, FM8 is just so much more practical regarding editing and functionality.
As for the ideal system: more CPU = more voices/DSP's. More mem = more samples, faster HD = more streaming samples, bigger HD = more space to store samples. So, there's really not much to tell here, except: "more is simply more".
