Hey everyone, I keep searching and going down rabbit holes but have a particular issue I think could warrant its own thread. If not, my apologies. I'm a professor in a college motion graphics program and have 6 2009 4,1 8-cores I want to utilize as we watch Apple flounder with their releases. I want to run some Octane and RedShift tests on one of the 4,1s (for starters) and am wondering what mix of OS, GPU, and drivers I can get away with without any flashing of computer or cards? I've kind of gone rogue from our IT department and am comfortable doing this with my own two 4,1s but don't want to take any risks with school property. Ideally, a 1080Ti would be great but not sure what the minimum OS would be that could run it. Thanks for any help.
