Hello, This forum about eGPUs is amazing. Please, recommend some setup to me. I have a Lenovo W540 20BH. It has QM87 Chipset, i7-4900mq CPU, 32gb of RAM, ssd, hdd integrated gpu is HD Graphics 4600 and additional dedicated gpu is Nvidia quadro K1100m. It has expresscard 2.0 and also thunderbolt port. What hardware would you recommend (or maybe a few options in different price levels)? Is it reasonable to invest into eGPU with a machine like that? What performance increase can I expect, compared to integrated K1100m? Can you estimate what kind of games would I be able to play and what details? Now, with k1100m, I am able to play witcher 2 on high details and lower resolution (720) (estimated around 20-30fps). Edit: I am aiming for cheaper variants. I do not need this to be portable (I will just have it at/under my desk). I will be using external lcd screen (displayport or dvi connector (i also have hdmi->dvi adaprer) so hdmi is also ok).
