planning on upgrading my Macpro Dual 5130 cpus to Harpertown ones. But I've read in various froums that it wont work, as apple hasn't release a firmware update for it. 
So instead im planning on going E5345s... anyone tried this, would this work? As I'd hate to waste money on procs i wont be able to use.
