Hello... Currently I have a Dual 2.0 PPC G5 that I'm looking to replace with a newer Intel Mac Pro. I'm wondering which one is the best bang for the buck. I was looking at the early 2009 2.66 quad core (MB871LL) because of price and that it seems to be better then the previous models. Or is it worth buying the new 64bit model (MC560LL) It seems the geekbench scores are fairly close so I don't know if I can justify the new machine being twice the cost. I don't want to spend more then I have to but at the same time I want something that will be usable for around 4-5 years. I do basic video editing with Final Cut which is ok on the G5 but it's the render and export times that are killing me.
