8.
And now do your homework on RAM prices, availability and configuration for the '09 MPs .
Indeed. And if you were considering the Quad MP09, then it becomes 4 vs. 8, AND with probably no ability to use 4GB modules, regardless of price. Paying $2,400 for a computer limited to 8GB is a bit of a deal breaker for me. And if you buy the octo, you're talking a lot more money, and being practically limited to 16GB unless you're talking even a lot more money STILL. I'm sure if I had infinite money I'd be interested in a 2.93GHz octo MP09, but in terms of value for the money, I don't think it can be argued that the MP08 is the winner,
unless you are sure you really never will find 8GB to be too little memory and don't need the octo.
On another note, I too, however, am unclear about the RAID comment. I would assume it would be just as easy to set up RAID on either the MP08 or MP09, but maybe I'm mistaken.
I also don't mind having two FW400 ports, as I have a 20" ACD and Apogee Duet and two external FW400 drives. I know, I know, I could always use adaptors or the proper cable, but it's just a small bonus to have FW400 ports directly on the machine.
Same comment goes for mini-display port vs. DVI. I'd rather have two DVI. But again, that was never a big deal for me.
Also, I like that the MP08 is very quiet, although I'm sure that would change if you changed the graphics card!
Anyway, for better or worse, I decided to jump on a MP08 before they're all gone. It will be here FRIDAY! YEE HAW! I've been wanting one for three years now. Badly.
