980ti burn too much power to be profitable even at 0.05 cent and heat too much .. A good budget choice could be a 1050ti.
They are definitely quite profitable at my power rate lol... plus i will be limiting the power limit of course, and likely will stick with just the one 980ti for now as I dont want to upgrade my power supply yet and am waiting on next gen nvidia launch before I get my next cards. 1050ti is a pretty trash buy for mining at the moment... why do you think i put GTX 1050 2gbs in my rig instead of 1050tis? because 1050tis cost like 250-300 dollars now and 1050 2gbs go for 100-150. And 1050 ti gets a whopping 30 sol/s increase over the 1050
