The people I know who make $ mining, on a small scale at least, almost all have some sort of "free electricity" set up, either through their school dorm, apartment/condo block, whatever. That's the only way I'd consider it, and I've been trading in BC since 2012.
nVidia is also now officially sold out of the Titan XP, only the $3000 Titan V is left in stock, so, so much for that way to go.
There are some around, but mostly inside already pre built systems siting in stock in places like Staples, Best Buy, whatever. I have a friend that bought a $2000 USD 7820k system from Staples Canada, just to get the 1080ti installed in it, and parted out the rest of the components - ended up costing him $750 USD, not too bad considering prices and availability right now.
When the new nVidia Volta cards come out, some say Q2 this year - I wonder how it's going to go so far as reserving them early. My current dealer, who has a dozen stores and focuses on gamers and small business, will only sell high end GPUs to someone buying entire systems right now, or very long term customers who are upgrading. They also have a shortage on PSUs, big time, it's as bad as the GPUs nearly up here in Canada, very, very hard to find a quality 850 to 1300+ PSU right now, glad I have a couple extra for future builds. Just wish I'd kept the GPUs I sold off in the last year, 2 1080s and 2 1080tis.
I hope nVidia and AMD up their production, only way to get some relief in the short term for the gaming industry.
