Are Apple's machines really more expensive than they used to be?

Not Apple's fault that there are no drivers for Pascal, the last nVidia GPU they used was a Kepler. The only reason there are drivers for the Maxwell based GPU's in the 900 series plus the 750's is that nVidia wrote them. nVidia may have seen some advantage to write the Maxwell drivers as their cards could be used in the 2009-12 Mac Pro's, but may have decided the effort was not worth it for what are now 5 year old machines.

This lack of support for Pascal GPU's might change if Apple picks nVidia as the supplier for discrete GPU's in a future Mac model. But Apple has been picking AMD discrete video for the last couple years for what they use in the dual GPU MacBook Pro's and the iMac's.
