I have been flirting with the idea of picking up a used 8 core 2.8 Xenon machine. I have found prices ranging from 1700 to 3000 for these machines depending on ram and etc... As far as I can tell 2K seems to be fair for one of these boxes. What do you think? I am also wondering if I would be better off buying a 4 core nethalem machine (refurb) instead? Its intended use is photoshop and video editing. Home video editing and semi-professional photoshop use. Thanks in advance for you comments. I currently have a 2.6(?) Core 2 duo 17' Macbook Pro.
