You know....I work on both PCs and macs and to be honest I don't give a flying crap what it is as long as it's quick, doesn't crash, and lets me get my work done. Yes, the new mac has a fast processor...yes, it has a very fast frontside bus...that's great...I'm happy for the folks at Apple but I wouldn't get so caught up in the specs. Things are always changing in the race for computer processing...buy what serves your purposes and bank account.

As far as RAM limit is concerned...Am I going to need more than 3Ghz of RAM anytime soon (the max of my board)? By the time I do, I'll be ready to switch out the mobo anyways. Just out of curiosity...can you buy mac mobos separately or do you have to buy a new box entirely when things start getting obsolete?
