Happened that many miners switched to X11, and new miner boosted hash for 50% and more. I had 47MH/s, now I have 68MH/s. Count that every serious miner did software upgrade, and we have 50% more hash now than we had 7 days ago with same HW.
i did not even update lol. I was still mining at 2.5 mh per r9 290. Damn.
Update n u will be surprised. But AMD is behind the game(Unless some serious update done on mining software. It seems AMD card full potential is not used yet). My cheap GTX 750 ti gives 2.1 Mh/s and My r9 290 gives 3.6 Mh/s and their price and electricity consumption is huge difference. I am going to add some gtx 750ti. I believe with GTX 750 ti its still bit profitable to mine X11(It is not as though much left to mine. lol). I have not count electricity consumption of GTX 750 TI but what I see from MSi afterburner seems to me 35-40w(shows 75% power usage).
