Greetings to everyone! I have laptop Lenovo Y580 with nice i7-3630qm(2,4-3,4Ghz, 6 Mb) processor but weak GPU - GTX 660M. I am interesting in eGPU solution, but am confused a bit in detecting type of PCIe in my free mSATA slot in laptop. I will be thankfull, if somene can give me tips, what kind of PCIe has my laptop and wich model of external GPU is better to use for best perfomance. Will I able to play 1440p with any of external GPU (on middle settings, lets say)? Thank you in advice, and execuse for my english.
