Well, I'll comment on my own post.
I've done it - bought a quad core. Specifications are with my signature. It flies! A comparative test with ArchiCad 10 shows it to be exactly 50% faster than the latest dual processor Mac - @ about 2/3 the cost. Only got it today so don't yet know of the bugs (if any) in the video card. However, when AC makes use of multicore processors, I'll be ready!
