1 shoe doesnt fit everyone. Apple should offer a Gpu upgrade for every line. Im saying a Gpu bump & stop the Mac vs Mac crippling.No matter how much we want Apple won't release a gaming mac. It's just not their market. They want to build computers for Joe Average, and Joe Cool who owns a music business or an engineering firm. These people don't play games.
The only reason I can see Apple putting really high end GPUs in macs is if nVidia port CUDA to OSX - or AMD do the same with their equivilant. These things do work.
As far as Apple thinks we ought to have enough fun making home movies or photo albums.
