I always wonder who these folks are that want to jailbreak for purposes other than unlocking.
I can't speak for anyone else, but I would jb for two major reasons.
I think the problem is not just higher production costs, but that the games themselves cannot take advantage of having 3 or more GPUs. The diminishing returns of having more than 1 GPU fall off harshly after adding the 2nd GPU.
So true... unfortunately the e-peen potential is limitless.
