been reading this site for a few weeks, have ordered the gdc and am looking at buying the gpu for a future desktop build but for now interested in playing around with a gdc
so far I understand...…
the m.2 socket is only X1 (wlan card)
may have to altar bios
the gdc is only X1
may have to altar drivers
all of which im prepared to live with 

so im new to gcd havnt seen many y700 example builds is there anything im missing will it be worth it should I have gone with a different gdc should I swap out my ssd for the x4 m.2 am I out of my mind what am I getting myself into???!!!
am i missing something???
so far just outlayed the money for the gdc so not in too deep
thanks in advance

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

@slurgen Also a Y700 owner here, I went for the M.2 NVMe (M key) connector with ADT R43SG. Everything works out of the box, no need to mess with drivers. For NVMe, you can increase the DMI link speed. Details of my build: https://egpu.io/forums/builds/2015-17-lenovo-y700-17isk-6th-4x-hq-gtx970m-2-nvme-adt-r43sg-tu-w10-1607/
