Well not to join in on the 'Dog Pile on Cyril' game here I'll just say that I've used both systems and, for handing sample libraries, the PC always seemed to work better at a lower cost. I used to compose Pop and Electronic styles and back then, five to ten years ago, Macs were the industry standard. In fact, they pretty much still are in Pop, Rock, and Electronic genres. If you go into any modern recording studio these days I bet they probably have the latest Mac(s) running. I read a lot of the trade magazines and they always have interviews with some young up and coming Pop Music producer. These kids go on and on about how Logic is best thing to come out since toilet paper. I don't think I've read a single interview where somebody said anything nice about PCs. In fact, they don't talk much at all about PCs as if they don't even exist. That has always irritated me about the Mac elitists.
However, I used to do film editing and the software we used (Avid, Final Cut) were Mac based and they ran very well with multiple things going on at the same time. Very well indeed. The PC, with Adobe Premier (Adobe CS3 at the time) was very buggy. It constantly crashed and it was a pain in a$$ to get anything done with. BUT when the Mac did crash it was usually a devestating and catastrophic disaster. I'm talking we had to wipe drives and reload everything from scratch. And, I'm sorry to say Cyril, our calls to Apple support were routed through Bangladesh or Outer Mongolia somewhere.
Say Vibrato, (Tanuj) if you're reading this do you own a Mac? I know you live in India so I was just wondering when you call Apple support do you get some guy in Sheboygan, Wisconsin, USA or Cork, Ireland or something? Funny how that works isn't it.
In the end, arguing about performance thresholds for Macs and PC's on Internet forums is a lot like competing in the Special Olympics. Even if you win you're still retarded. So why bother?
