Nope, I have a 166 MhZ Pentium II; all of my most FUNCTIONAL pals use Macs aside from the most technically/musically adept ONE who is too busy as a programmer to get to it for now; and I'd be perfectly happy to upgrade if I thought it really necessary. Deal is, I'm sure I'd be wiser to get a basic MIDI card and a program such as the aforementioned & pretty well proven SoundDiver in hand rather than sweat the rest. I have no real interest in plug-ins as a rule, so I wouldn't be straining my setup much. The day I can afford a proper card, the software AND a 2nd 01/W of some kind so I can REALLY let 'er rip, you'll know, 'cause the resultant big squeal of delight will cause minor damage to your windshields! Now, if I can just get to sounding even HALF as lush as Deep Forest, Heaven will have lost it appeal!
