Hmm, In my opinion if you are looking for a general use or gaming PC you should deffinatly go for a PC as they do tend to be much easier about the upgrading and the OS is is more compaitible with games. Wheras if you are going to be designing graphical things or doing most kinds of design work I would totally suggest the mac, its supposed to be uber at that kind of stuff. Wheras if you wana be a total geek, virus free and completly customizable and build your own pc parts you should invest in Linux, it's free and very annoying for hackers.
