I'm thinking of changing the 2 proc. G5 Power Mac and upgrading to an Intel Mac Pro. I've read the reviews on Macworld etc. and the 8-way system does not seem to offer a significant advantage for most tasks over the 4way (All gains seem to be 10% or less I think). So..... What apps CAN take advantage of these extra procs today? (I mainly use Aperture, Final Cut and Logic - hobby only not pro basis). Anyone got any views on whether 2 4-way systems might be a better investment? (Leaving the 2nd system to act as a slave node to process in the background) What is the best graphics card option for the above? (I plan to drive 2 * 30'' at most). Thanks.
