Hey guys. I am a noob , I've only started reading about egpus about three months ago and I was amazed by the capabilities they offer. What i ve read has shaped my search for a new laptop, turning me away from looking for a gaming laptop to now mainly looking for one with an a thunderbolt 3 connector to use for a future egpu setup . I m not interested i buying a Mac .Mainly with the help of this article https://docs.google.com/spreadsheets/d/12G1VTFWkTL5tb8nxUAtnDHwTLyya9I3Vw-OXXrIN4e4/edit?pli=1#gid=0 I have come down to this product http://www.dell.com/us/p/xps-15-9550-laptop/pd?ref=PD_OC In fact it is a bit expensive for my budget but i can keep it around 1000£. I m mainly interested in the configurations costing1200$ and 1500$ as they are more than enough for my needs. So here are my questions: 1.Both the i5-6300hq and the i7-6700hq processors are the same except from the clock speed (3.2 and 3.5 Ghz at turbo respectively). Will that difference be observable in everyday use or be a bottleneck in gaming. Is a core-u processor even worth considering for gaming? 2.I don't have an external screen to use .Is a thunderbolt 3 egpu setup, using the internal screen of the laptop, possible if both an igpu and a dgpu are present ?(in this case igpu=Intel® HD Graphics 530 and dgpu=NVIDIA® GeForce® GTX 960M with 2GB GDDR5). Does an egpu setup, utilizing the internal lcd ,require for only an igpu to be present? 3.What role does the BIOS play in the feasibility of an egpu setup if not only in hot-plugging? 4.Are there any issues with Optimus and Windows 10 that i should be aware of? In my opinion one of the most promising steps for a thunderbolt 3 egpu setup has been made with the Razer Core. But still everything is pretty much up in the air right now and there are no actual products available in the market .These are the reasons that have kept me from actually buying the for mentioned Dell xps 15 as i don't wanna pay for a premium product with a premium connector that will not be able to do what i intend it to . This article has only made my confusion worst http://www.pcgamer.com/the-razer-core-looks-like-the-graphics-card-enclosure-weve-been-waiting-for/ Thank you for your time and thank you in advance for your help ,Bill
