I would go for the PC for the following reasons..
1) Mac uses a subset of PC hardware but you pay significantly more for it.

2) Mac OS X less secure than either Windows Vista or Linux. Mac OS X was hacked in 30 min., 2. min, in 2006, 2008, 10 seconds in 2009.

3) Although Mac currently does not have as many Spyware/Viruses they are on the rise.

4) Linux has more cool effects than Mac OS X and can do every effect Mac can do..

5) For graphics/video production PC is equally as good. Each company has it's preferences but Dreamworks Animation uses PCs

6) All computer manufacturers have problems but there are plenty of problems with Mac.

7) Follow the logic:
Facts...
A) XP and Linux are faster than Vista, Mac
B) OS X runs faster with more memory,
C) Vista runs faster than OS X on Mac with 2+gb http://www.gadgetell.com/tech/comment/vista-runs-faster-on-mac-pro-than-apples-os-x/
logical deduction from facts above
- A PC with Vista 2+gb runs faster than Mac OS X with lower specs but even with higher specs since a Mac uses the same components as a PC.., remember Linux and XP run faster than Vista..
ANOTHER OPTION: Dual boot with LINUX - You don't need to choose Windows or Linux... have both at no extra cost..
