My pair of GTX 960s are currently pointed at Nicehash (they're in my "backup" gaming machine so Win7 not LINUX).
Machine also has a GTX 950 also mining to Nicehash.
Current earnings are a little over $6/day for all 3 cards combined.

Machine as a whole has been a consistant $3/day or more earner for pretty much all of the last year, without using the A10 APU for mining at all.
