This is an honest question. Why would you throw money away buying a bleeding edge graphics card when you can buy 3-4 other cards for the same price with a combined hash rate that will shit all over that card for overall value and hashrate?
edit: You can buy 5 RX470s for the same price as the one Ti.
I play games on my PC, so i like to have a high end GPU to power my 144HZ 1440P monitor. I also dont like having 3-4 spaces taken up for multiple GPUs when i can have a powerful one take just one slot and use the same amount of power and probably less vs the 3-4 other cards. Another reason is once the ROI (~5-6 months for a single Ti to pay for itself) is done i make a lot more profit from there on out vs going cheap and multiple less powerful space hogging cards
