I am starting to do my research on eGPUs. I really want one. My problem is I have apple displays. One is the  Apple Thunder bolt display and the other is an Apple 27 inch Mini Display port. Is there a GPU I can use with one of them? 

I am also looking at the LG 5k display but I cannot find a video card that will work with that as well. Is there one? 

thanks for looking.

Hi!

 

You can use any 900 gtx series that come with mini display ports. They will all work with your monitors including the 5k lg one. Physically the mini display and thunderbolt are the same. If you want to use your eGPU exclusively on MacOS stick to 900 gtx and redeon RX 460/470/480. You won't get drivers for 10xx series from nVIDIA on MacOS. 

Buy your gpu from Amazon. Try and return if not happy. You can check my setup (in the signature). It can hold up to 3 5k monitors. It currently has only 2 4K but technically can use way more.

Thanks for the help. It looks like the mini display port will work but the thunderbolt will not. Thunderbolt is the same port as mini display but that work different. 

Do any of the card have USB-c connectors for the 5k display?

@Kunadiso, the Thunderbolt display is best avoided for eGPU use since it would be connected on the Thunderbolt chain an so uses Thunderbolt bandwidth for display traffic.

To maximise eGPU performance use a display with a connector you can attach directly to your  eGPU output ports. Then display traffic goes straight out from eGPU to the display via the cable between them.

I have a question. If you plug in the Apple 5k monitor to the mini DP port of your GPU will still use the bandwidth from TB (still seen as TB chain if its not plugged in the TB port of the enclosure)? Shouldn't been seen as a DP connector instead of TB?
