Question for Mac and FCP users

Hello,

I've been a PC oriented person since I ever used a computer, but I'm now interested in getting a Mac Book Pro with FCP. I've always heard that for PC NLE systems, the best thing to do is to get one system for editing, and another for personal use. I've heard lots of stories where ppl use one computer for both uses, and with all kinds of codecs polluting a system, that can result in hours of headaches, workarounds, heart attacks and temporary blindness.

But for Macs, particularly the Mac Book Pro, is this necessary?

I'm interested in doing this.
1) MBP with Mac OS X 10.6 Snow Leopard (for FCP editing , personal, and possible gaming use)
2) Parallels Desktop 5 (to run Windows for personal/gaming use)

Thanks for the help,
Ryan
