currently have a 2007 8-core 3.0ghz mac pro. looking into selling it to snag a new 2009 2.66 quad-core. I use the computer for a little bit of everything including some gaming. nothing to in depth with anything I do. I like to dabble in some video/photo editing, but also like to fire up bootcamp and play some crysis. question is....assuming I can break close to even on price, am I sacrificing too much by simply wanting a new mac pro? Is it best to stick with what I have? Or would a new one be quite the upgrade? thnx
