Woah, thanks for all the replies so far guys -- The reason I was originally going to look at an Nvidia card is the drivers. I've always had issues with AMD software. My history with AMD/ATI cards are as follows:
* An ancient Radeon 5850 * Mac Pro (2013) FirePro GPUs On both of these cards, I have had issues with my desktop wallpapers turning black, explorer windows looking incorrect, and mouse cursor corruption with dual monitor setups. This persisted across multiple windows installs, and countless driver versions. Has AMD fixes these issues with newer cards/driver releases? I'm not too concerned with DX12, as I think by the time it's really needed I'll be looking for another upgrade anyways.
