Hello everyone! I wanted to ask a question pertaining to my curiosity about replacing my current mac pro with these new MacBook Pros. My concern is mainly about the Ram. Currently I am using 18GB of the 800-mhz type, and need it for computer rendering. Most of the time, about 14-GB is all I need. I am wondering that if with 8-GB of the 1333-mhz Ram, would that rival my current 18-GB? Or is capacity much more important than speed? According to GeekBench, these Quad-Core MBP's benchmarked much higher than my Mac Pro Early 2008, 2.8-GHZ 8-Core. So it would seem that would suffice quite well. Thank you!
