Buy an Alienware or Sony if you want quality. You get off cheaper and have a much more flexible system.
A mac is a good choice for rich people who couldn't be trusted to program a VCR.
Macs: Good customer support, compatible hardware, no fuss as you can't put something on it that won't work, Expensive
PCs: Customizable, generally bad customer support, if you don't know what you're doing you'll have problems, Cheap
Buying a Mac makes about as much sense as cutting off your balls with a rusty pair of scissors.
