Hey All, Budget is under 300 but would prefer as cheap as possible. It's for a professional recording studio environment not for video professional use. I'm looking for a solid relatively modern Single Slot GPU that works OOB with OSX Sierra+. It's a weird situation where I need to occupy 3 PCIe slots in the tower with other cards to get the most performance out of it. Only requirements are that it can push 2x 1080p monitors with DVI connectors (I know I'll need adapters for this either way, which is not an issue). 3 Monitor outs would be a plus for future use but I know that's pretty rare on a single slot card. I could also use a recommendation on the USB 3.0 card but there's already a ton of info on those I can look up! I'm looking to have x1 Avid HDX Card x1 Universal Audio Octo Card x1 USB 3.0 x4 Port Card x1 Single Slot GPU I have installed higher end NVidia cards (GTX TITAN X/XP and 1080/ti) on these towers before for video professionals but it gets complicated with updates breaking the driver every time there's a ".X" update. I can work around this if there's a solid option but would rather a native AMD card if possible. This will be for an audio professional with no need for heavy GPU usage just to keep graphics running smooth on both monitors. I really appreciate your help!!!
