Hello Ok maybe I'm a little late and this post might seem outdated as soon as I post it. But from what I read, X11 coins are supposed to be ASIC proof and to be mined by GPU for a long while. After breaking a tooth on Bitcoins, and then another one on Litecoins, I thought I finally had found the coin that I would be able to mine. I kind of guessed that my GTX560TI wouldn't make it to the first Darkcoin, but did some testing with it. Result is, 1400Kh/s : after one whole day, I earned 0.03 DRK and spend $0.44 in electricity. So yeah, I definitely need a new GPU. Let's say I get a Gigabyte R9 290 BF4 Edition - 5.63 Mh/s, seen here: http://wiki.darkcoin.eu/wiki/Mining_Darkcoin#GPU_Mining_Performance_Charts => at best 0.24 DRK ($0.48) - 300W probably underestimated after reading some tests. => $0.77/day I'm loosing $0.29 a day using such a good GPU. So where is the trick?!
