me!
last year i was using an iMac w FCS2.
to be honest, i want using all of the STUDIO,
i wasn't using Motion or Color, for instance.
but for editing, it's great.
i cut two features on it, no worries.
there's not a lot of heavy fx in what i do,
but some CC, simple compositing (pic-in-pic sort of stuff), titles.
plenty of RT on the iMac.
what sort of work do you want to do?
