Macpro 4,1 machines, single-processor are going between $1,000-1,200 here in the Toronto area. If i'm looking for the fastest thing possible (for logic audio), would it make more sense to: 1. wait it out for a 5,1 2-processor machine to hit the sub $2,000 mark 2. go ahead and get it and upgrade the EFI & cpu with a 6-core 3.x Ghz chip (now we're at around $1,800) and add ram (more $) 3. keep waiting for the 6,1 mac pro I'm not in dire straights to get a new machine; my mbp has actually proved to be faster than my 3,1 (geeks at 10,999), but can't go above 16gb ram as no one makes 16gbx2 chips ...yet? in the same situation, what would you do? wait it out? I have funds set aside to do whatever, but part of me thinks it's good money thrown after bad if the new pro has all the stuff we've been pining for.
