I figure this needs to be in a new thread, since it's a backwards situation. I have a GTX 980 Ti from MacVidCards in my 4,1->5,1 Mac Pro, and it's working fantastically in every way. Looking to the future, if I were to build a new PC video editing system, how would this MVC flashed card work in a PC with the current version of Windows? I understand that it's nonsense to buy a PC card, flash it to work in Mac, and then use it in a PC, but I'm thinking about the prospect of repurposing it down the road someday, if the Mac Pro dies in a way that makes it too costly to repair, or the CPUs just get too old to be useful. By then, maybe the 980 Ti is also too old, but still curious. I'm wondering if the flash overwrites needed data for a normal PC in Windows to run the card normally.
