Hello everyone and I hope you're all doing well. While I've read quite a lot about BitCoin's and Crypto Currency's in general, I have no experience with mining and would like to get some input from those more experienced. I've been reading a lot about GPU mining and from what I understand the higher "GH/s" you have the better chance you have of earning BitCoin's. In one of my computers, I have 2 Nvidia GTX 780 TI's running in SLI and was wondering how well/effective it would be to mine with these cards. Is there a way to determine what my hash rate would be? The reason I'm asking is because these two cards were very expensive and I'm sure mining would put a lot of wear & tear on them and I want to know how much potential I'd have to make money mining with these cards. Any input or suggestions would be appreciated!
