Apple rolls out 8-core Mac Pro

2800 bucks is really less than I would've expected with this type of performance - there are boutique PCs that are much more expensive - like 5k-8k.

I would want a better GPU and more hard drive(s) and space

Moving to Intel was, I think, a move that has really helped Apple.

Dual booting Windows and Apple is something I'd like to see in my future!
