All - Looking for a quiet and competent GPU to install in a 5,1. Currently has a Mac version Radeon 5870; the fans in it are too noisy for where the MP is located. I've searched some, and saw a statement that most modern GPUs are inaudible, but could use some reinforcing feedback (a friend of mine keeps it in his bedroom, hence the need for quiet). Budget is probably anything up to about $400 or so. Have looked at RX-580/GTX-1060, have read about the foibles of nVidia 10 series drivers. Would a W7000 or something similar work?
