Like everyone else here I was highly disappointed with the Mac pro "update". I've been using a G5 in my home studio & was trying to wait for a new pro because I didn't want to pay top dollar for a 2 year old machine. Since the update was a disappointment I've decided to buy a used machine from eBay. Im having a hard time deciding on either the 2008 2.8ghz 8core & a 2009 2.66ghz 4core. Any help would be greatly appreciated they are very close in price I just want the best performer for my $$. I'm running protools 9 & will soon be upgrading to 10, with many plug ins & soft synths. Im looking for the smoothest run for producing with my new machine.
