How can I know if smth will be upper than e-gpu limit ? What kind of stats should I compare. For example the egpu.io buyer's guide advice me to buy akitio node which on his page do benchmark with gtx 1080. The bandwidth of an gtx 1080 (From the nvidia website) is 320gb/s and the akitio node can handle "up to 40gb/s" but on egpu.io it's 32gb/s. Which mean there's some loose ... ? Does it worth a gtx 1080 as egpu or will it be a waste of money ?

I was wondering if, now In 2017, is it worth having an laptop to replace desktop. Before saying "Huh, bUT gAmINg oN LAptOP sUCkKk !", read my current situation. I have an old pc (desktop) which run game on low quality but at 60fps. It's time to change. I have an old laptop which does the job, but I'm looking to replace it too. And I'm looking for having only a laptop. Like an dell xps 15 with all feature (Idc about the price, I want a good laptop that's all) and be able to put it at home, plug my laptop to a docking station and to an external graphic card. It would be awesome, that's mean I can develop on my arch linux without care about the gpu power and playing (on heavy game) on windows at home with 2 monitor, and all is on the same pc. Now the question is: Is it possible ? I don't want one of those gaming laptop (that's ugly and look strange to take it at job.) Thank you for any advice. Alaanor.
