Is it worth buying a 3.2 Ghz 8 core MacPro on Mac mall with the discount? http://www.macmall.com/macmall/families/macpro/ (the two last ones at the bottom) I would just be buying it to buy it. Is it cheaper to buy the 320GB HDD and upgrade via New Egg to 1TB or just get the 500GB model? Is it worth it with the ATI Radeon HD 2600 XT with 256MB of GDDR3 IDk i want the base card? I like Nvidia better personally Than there is the Apple refub with 2GB of ram and Two Super drives and a 500GB HDD for even less. Any advice?
