I am reposting this because I don't think anyone saw it in the place I originally posted it) I am trying to decide whether I should keep a mac pro I have acquired. It has 2 6 core 2.66's, 24 gigs of RAM, 5TB on 3 drives, two radeon 5770's, about a year of applecare remaining. It's great to use, but the speed, even though the CPU's score over 7000 passmark scores (and there are two of those), doesn't feel as fast as my i5 with 16gb of ram and one nvidia card (forget which one). In Photoshop, the zoom is super smooth on the i5, and jumpy on the mac Pro. Apps don't load too fast, and the machine is slow in starting up. However, the vmware fusion windows 7 machine in the mac pro gets a higher windows experience score than my fast i5 desktop and faster than my fast i7 laptop (both score over 7000 passmark scores). Maybe there aren't many apps that actually make use of all the cores. Should I keep it or get rid of it? I know what they retail for, but what is this machine really worth? What would be an ideal purpose for this mac? Thanks...looking forward to reading what you all have to say about this.
