I am currently running Logic 9.1.2 on an 8-core, 3GHz Intel "Clovertown" Mac Pro however I am considering upgrading to the new 8-core, 2.4GHz Intel "Westmere" Mac Pro. I am considering an upgrade because I've noticed that my rig has been slowing down and my CPU is getting bogged down - and I figured that since the Mac Pro is 4 years old it may be time for an upgrade? I am running 8GB RAM and am heavy-handed with VI's (Omnisphere, Trillian, Native Instruments Battery, Electri6ity, Vienna, etc) and plugs (Gtr Rig, PSP, Soundtoys, T-racks, etc) I read a previous post that recommended going with 8-cores over 4, however I am wondering if the Westmere processor is markedly faster than the Clovertown (even though it has less GHz). Can anyone enlighten me??? Thanks!!!!!!
