Hi, after being tired of waiting for a refresh, I purchased a 2010 2.8 Mac Pro refurb, and I am now fixing to do an upgrade or two to improve performance. Ideally I would like to do this in a best bang for buck forward. At the moment I am running with 6GB RAM, stock 1TB HD, and the 5770 GPU. I am hoping with some upgrades I can get some blistering performance out of this unit. If not possible compared to my previous setup (see next paragraph), or cost effective, back to the store she will go. Main uses are for Adobe Flash CS5.5 animation for broadcast, and exports to 1080p. Almost went iMac, but was on the fence. Worry of course stemming from the 2011 MBPro 2.2 i7 8GB Ram I was previously using; whirring fans up and down when working with large files on a timeline. Lots of copy/paste crashes. Didn't want that repeated in the iMac. My thoughts that with the extra airflow the tower allows, the spinning balls/crashes/grey screens would be minimal.
