Hey all, I was wondering how you could see if a GPU is descent for mining? I figured some of us (including me) dont have the money to spend on multiple R9 290 cards. So in my case i searched the internet for some used Gpu's (bought 2 HD6950 because they did perform pretty ok with srypt mining) For decred they didnt work so good tho. My question really, What are the speccs you need to look at to know if a card is descent for mining decred? For example the HD 6950 has 2GB, 800Mhz Core, 1250Mhz Mem. His cheaper brother (the HD6870) has only 1GB, but has 900Mhz core and 1050Mhz Mem. Which one is better? Get my point?
