okay so im new to macrumors and this is my first post. im sorry if this has already been asked but... im interested in buying a mac pro. i was wondering if i should save a little money and buy a used mac pro... maybe a year or two old... (i have found a late 2008 quad core 2.66 model with 8 gb of ram for $1000) and upgrade the ram, hard drive, video card, etc. or should i buy a new base mac pro with my developers discount? about $2000. any advice is appreciated.
