what GPU for rMBP mid 2012 (TB1)

[dude1]

Hello,
Soon I'm thinking about doing an eGPU set up for my retina MacBook Pro primarily for gaming in bootcamp but also for the odd did a bit of video encoding/editing and such on the Mac side.

I'm thinking about going with the the Akitio node using the thunderbolt 3 to 2 adapter from Apple because I imagine my future computers either Mac and/or PC will have thunderbolt 3 so it's my way of future proofing the enclosure or at least future me will have one less dongle.

 

My main question is what GPU should I look at buying for my MacBook?

I imagine with thunderbolt 1 being major bottleneck that going out and buying at 1080TI would be a waste of money.

Basically is there're a point where a better card won't make a difference e.g. 1060 will run the same as a 1050  or 970 etc. because of the thunderbolt bottleneck

Primarily i'll be playing on one of my 2560x1440 Display port monitors but may want to us the internal display at times eventhough i read that makes the bottleneck worse

 

thanks

 

ps. Here is another possibly stupid question, I know that thunderbolt1 is 10GBs and thunderbolt2 is 20GBs,  is there any device that i could attach to aggregate 2xTB1 into 1xTB2 to futher help with the slowdowns?

gpu wise anything from 1070 and lower will just do fine. using the internal display is what makes tb1 even worse a bottleneck. my best experience is display port to minidisplay port to led cinema display. that'll boost performance.
