how are these for mining?  is the vram decent? how much should i expect with 2 of theses farming with nicehash or winminer?
 thinking to buy 2 of these tommorow and start up a small rig, then buy 2 more next month, are these decent? or should i put a little extra in and get a gigabyte or EVGA?
or just aim for a 1070?

any info will greatly help! thanks

EDIT'''''''''''''''''''''''''

have bought all my components and will show you guys the outcome soon!

i'm also in the UK, and have been interested in starting to mine too, i have around £800 saved up, was thinking to start small, with maybe 2-3 GPUs ( 1060s 1070s maybe) i already have a old pc case to put them in and plenty of spare RAM and CPUs, the only thing i will really need to pay for is the eleccy at around 0.12 pence per kw.
any advice guys? i`ve been watching some videos but i doubt that would make me ready for it haha
also been reading the forum for a while too and seems nicehash was good but got hacked? so not sure what to use! took me like 2 days to sync my bitcoin wallet lol

any advice would be appreciated!

tl;dr
is mining with 2 GPUs profitable?
i want to start small and eventually increase
