Hello, I am in a situation where I must purchase a nMP before the end of 2015. No choice... have to buy. This is what I have spec'ed out: 6 Core Processor 512GB SSD Dual AMD D700s My question is... If a Mac Pro refresh hits in the next few months, what is out there that would be significantly faster than the Dual D700s? Am I safe in spending the extra money for the high end card, or will a new Mac Pro blow that away? I know the move from Ivy Bridge to Haswell would be a minor bump, but the GPU is what concerns me the most.
