What I still don't understand is why they don't offer BTO dual-CPU with one GPU or vice versa? This became such a specific machine that is either mostly show off or for a highly specialized 'niche' market with programs already taking advantage of this config.
I agree Apple should offer Dual CPU config also .. make size little bit big I don't mind. Bcz Software companies will take time to take advantage of openCL .. specially like maxon(C4D) / sidefx (Houdini) / autodesk(Maya)
