Jase you troll!
PC stuff is cheap because of good old capitalist competition!
I think the Mac superior quality / stability argument is pretty obsolete these days. It's often just a marketing advantage for studios to say "Yeah, well, we have Pro Tools."
Mac is still certainly an industry standard in audio / video, and I'm sure that production companies demand knowledge of the Mac as an absolute pre-requisite for new employees - as I believe you can personally testify.
But hey, have you seen the Spy Kids movies? All done on AMD. That was hardly an amateur production with a budget of $37m, and they chose to do the animation and effects on PC. Clearly Mac doesn't have the monopoly in pro media production anymore.
That AMD Opteron is a phenomenal dual core processor. The 2.2G model is just €140. So for under €200 I can upgrade to a 2 x dual core mobo and chip. My ram and PATA hard drives are still compatible. Not the latest pieces of kit, but quite a leap up from my old P4 2.4.
