Current setup is 2x4x3ghz 16gb RAM and 4 500 gb drives in a Raid 0 setup (backed up very friquentelly via TimeMachine and Raided ZFS fileserver). Vid card is the 7300 cause I found the 4870 too loud. My speed drug of choice is Xcode, pretty much the only thing I care about. Though I Also use VMWare and Aperture less frequently. My desktop rule of thumb is that I like to see a 4x speed increase prior to updating. Any idea if the new 12 cores are there? I know they aren't out yet but there are some reviews on these chips and someone more knowledgeable then I might know how much faster these are vs the older ones.
