  There was a paper published last year in the Journal of Computational    
Chemistry (J Comp Chem v.17 no.11 p.1385-86) entitled 'Viability of
molecular modelling with pentium-based PCs'. I don't recall the details
but the gist of it was that they ran CHARMM on various platforms and found
that a 200MHz Pentium was faster than a SGI Indy with an R4600 processor for
running CHARMM. We use CHARMM for calculations on proteins and my 
supervisor is planning to buy Pentiums rather than more Indys for running

 CHARMM has been ported to the PC but I don't know under what OS; I would
guess Linux. I don't know about X-PLOR, not being a crystallographer.

    Hope this is of some help,
