kcspkd, you can install and use a GTX card such as the GTX 1080 in your Z640 without any problems. GTX cards work as a charm in any Z4xx/Z6xx/Z8xx workstation. I have a GTX 760Ti in a Z800 and a GTX Titan X Pascal in a Z440.
This.
They are not supported becase we do not test them in our workstions, but they work fine.
However, you cannot SLi GForce cards in Workstations so you will be stuck with a single card.
(Ok, you can installed more than one card and have multimonitors but they will not SLi.)
