Background I have used PCs for years. I did a degree in Comp Sci and never even touched a Mac just Windows and Linux. I always thought of them as pretty looking but slow and unable to run anything. However with the new Macs that run on intel and use NVidia chips they ARE a PC they simply run a different operating system. I massively prefer Leopard to the car crash that is vista and it seems that Snow Leopard will just nail the coffin shut. A year ago I bought a Unibody macbook pro but I am thinking I would like at some point a monster desktop machine, (mainly for games). But that mac pro's are horrendously expensive and very limited in what you can put in them. I can built a PC which would destroy a Mac Pro in benchmarks for HALF the price or less. The Question If I built a monster PC could I dual boot Windows and Leopard or Snow Leopard or will the games PC forever be a windows machine?
