Sorry, I think i miss communicated.
I have a MacBook Pro, MacMini, Dell Laptop, DIY PC Gaming-Class, Toshiba Laptop (2x)
Each performs for what I expect, and all perform well. The ones with more memory do a superior job at image editing, the ones with less, do not do as well.
I run a mix of Windows 95 to Vista and Leopard, and Tiger...
I did not mean to imply that the MacMini works as well as the MacBookPro, nor the Gaming PC, nor my Dell Laptop... (my two toshibas are quite old, one is dedicated to the aquarium, the other is the kids mainly)...
From my experience, you can get better with a PC than with a MAC... Though with a MAC you get easier/simpler/"it just works" kind of stuff... so long as you want to do what someone decided you wanted to do.. (which I do, so it works)...
If they fix iTUNES, MAC will rule my household... but until iTunes can have a server/client model and run off of multiple drives instead of just one I'm not going hard-core(er) mac...
