I'm buying a 2010 refurbished Mac Pro today to replace the 1,1 I have. I don't want to spend even more money for ram on my 1,1 hence the purchase. 16gb isn't doing it. Noobish questions I have... 1.) Eventually I would like to do a processor swap(probably pretty quick). Would this computer be a good candidate? http://store.apple.com/us/product/FC560LL/A/refurbished-mac-pro-28ghz-quad-core-intel-xeon 2.) I notice the 1066 ram.. Should I get faster ram right off the bat if I plan on doing the processor swap? Or does it even matter? 3.) I am guessing this purchase would be a tremendous jump from 1,1, would I notice an improvement in processor speed since this is a single 2.8 compared to my dual 2.66 I have now? Thanks for your time guys and gals.
