Games?

I have a hard time envisioning what would require a GPU beyond what's available on an iPad.

My NeXT cube had a 25 MHz single core CPU, no GPU and a megapixel display and was pretty darn "desktop grade" or rather "workstation grade". OK, higher resolution, color. But also a 2+ GHz dual core (later: hexacore) 64 bit CPU and a pretty darn powerful GPU. Where are all these cycles going?
