I'm upgrading two Mac Pro's. I did one already. Quad 5,1 mid 2010 2.8. I put an X5690 bringing it to 3.46. The other CPU arrives Tuesday for a 4,1 2009 quad 2.66. I'm doing the firmware the dropping in a w3690 bringing it to 3.46. Both have 32 gig ram. At the end of the day will both MPs be the same? Dumb question I know but the 2.8 should have no tiny advantage over the 2.66 any more, right?
