Yes I know there are rumors of a 2013 'update'. But as I've found with macs... it's best not to hold your breath for future products. I've seriously considered the 6-core 3.33 Mac Pro that everyone says is the sweet spot for bang to the buck. But I find myself hesitating because of the lack of an upgrade path. I doubt there will ever be a faster CPU and only 4 slots for memory (3 if you want it fast) doesn't sound very appealing to me. I used every one of the 8 slots on my former 2006 mac pro. I keep coming back to the 8-core westmere that's being sold as a refurbished unit on mac's website. Yes I know that the 2.4ghz 8 core will be slower than the 3.33 6-core. But at $2700 it's a good price and has a serious upgrade path... Doesn't it stand to reason that I could rock that for a little while being much faster than my old 2006 mac pro. Then at a later time upgrade the CPU's to dual 6-core xeons for some extra juice in the future, along side a possible 64gb ram upgrade. The 8 core just seems to have more life in it for the price, even though I know out of the gate it will be slower than the 6-core 3.33. Am I wrong in my thinking about the potential upgrades?
