Bether to buy 970 cards. More hash, bether density
Performance rough numbers with the new miner(x11) build 21
980 9500 KHASH (+-500KHASH
970 7500 KHASH (+-500KHASH)
780ti 6100 KHASH (+-500 KHASH)
750ti 2850 KHASH (+-200KHASH)
I testet build 21 on the 650TI yesterday and it was able to find shares. (quark). Compute 3.0 is probobly fixed for most algos now.
With release 21 980s boosted in X11 to 9800KH/s with +170MHz Core, very good.
Cheers
