I know how it feels, I have been dealing with it in the past few days I own an even older model of the Nvidia GT series,  I got the Geforce 9400 GT. So acording to the thread I just lose any hope on getting this GPU to mine somethingBTC. Well I Think I will save some bucks to buy a better GPU, any recommendations from you? I now restrict to a budget of $200 if that helps. Thank you all for reading my comment. Keen to keep learning on mining stuff and Cryptocurrency.
