Yes, I read the Nvidia FAQ thread, so please don't flame me... Can't seem to find a definitive answer whether the NVS 510 (Kepler) will work in a Mac Pro 5,1 - or alternately the Quadro K1200 or the M2000 (Maxwell). System: Stock Mac Pro 5,1 on latest El Capitan My needs are: A low profile card to replace the stock Radeon, so I can get 1 PCI slot back for other things 4 concurrent monitor support, up to 4K native 3840x2160, DP 1.2, 30Hz is fine, 60Hz is great Ideally 4 Mini DisplayPort connectors, or 4 regular DisplayPort. No need for old school DVI. As long as it works properly with sleep/wake, I'm fine without EFI/boot screens, but if they're supported, it's a bonus. Don't need very much re: 3D acceleration or CUDA, this is NOT for gaming There are anecdotal posts in other threads regarding the NVS 510 working with the native Apple / Nvidia web drivers; can anyone confirm this? Any magic combo of drivers needed? Thanks in advance!
