You forget also dyshade that some are even experimenting with tripple processor systems in PCs especialy athlon 64 fx's. Even a single 64 fx has been proven right now to out preform by far any other processor on the market with no contest. Infact the only media I have seen an apple system garuntee to outpreform pcs is use of CAD (computer aided drafting) programs. Beyond that PC is a farm more versatile and pwerfull platform as Ive seen.
