I got my Mac Pro 3.2 GHz 2 processor quad core with 16 GB RAM and RAID enabled 15000 rpm SAS drive on oct 29. I am experimenting with 3 monitor setup, two 30 inch Apple Cinema displays and one Samsung 22 inch display.
Let's see how much productivity I can get from this new setup. Only gripe is the hissing noise of the fan. I don't know if it has to do with the SAS drive. I will post my setup photo on rubyplus.org soon.
