I'd stay away from GPUs that have had their driver support discontinued something like five years ago in favor of something that should have driver support for the foreseeable future like a GT1010-1030. Nvidia hasn't culled its driver support in a while and the drivers are getting ridiculously large, seems overdue for a trim or at least a split IMO.HD5450 also works well. An HD4350 can also work with win8 drivers.
