If i get a mac pro my dream machine would be 2.66ghz with 2 gb RAM and an 1900xt but im not sure if i can afford that. SO, do I get the 2ghz with the 2 gb or the 2.66 ghz with the 1 gb. 2 dual core 2.0 ghz processors is still a hell of a lot of power. I'll mainly use it for gaming, day to day things, and probably video/movies.
