I'm looking for some buying advice, I'm having a hard time deciding on what to get. I have a couple options i'm looking at, but the bottom line is no matter how I turn I will need a Mac. So, i'm looking at the Mac Pro, but I don't have the 2500$ entry level price. So i was looking at a 2006/08 Mac Pro off EBay for around 1200$. I would like a Mac Pro because in the future I want to expand the system and add more space/better video cards. Now, I know that what i do is important in these decisions, so allow me to describe. My main task is programming, I program websites, video games, programs, Mobile Apps. I don't do any 3D Design, or Photoshop design. I do however take designs and export them for web; I also do BSP map editing. So, theres no rendering here. If I got a Mac Pro 2006 would I really see a difference in speed from DDR2(06)/DDR3(08) I doubt the processors would be a problem because I'm coming from an AMD Single Core. I guess i'm asking, would I really benefit from the features of a 2008.
