Hate to add another which vs which mac shopping thread but ...here goes. I'm looking to complement our 2 quad core mac pro for HD FCP editing. Basically a system to do some light field editing, then finish up at home base. There may be times (out of state) where some video work needs to be done quickly though without access to the home machine. I was saving up for the 2.8 15" but now reading about the new cpu bumped 15's possibly being able to take 8GB RAM, my interest is peaked. For my needs and with a budget of about 2 and half grand, should I get a refurb 2.8 or new 2.66? How would FCP rendering/Compressor be influenced by a 5% increase in CPU speed vs 33% increase in RAM (8GB vs 6GB). I'll of course pop in a SSD probably this fall. Thanks in advance!
