Mining x11 (Logic Coin) for the first time with ccminer-v1.0 and here are my results:
ccminer30
660Ti SC --> 1750 khash/s
660Ti ------> 1670 khash/s
780Ti SC --> 3040 khash/s
ccminer35
780Ti SC --> 2700 khash/s
So the big iron runs compute 3.0 better than 3.5.
Interesting results.
I just run the ccminer 1.0, X11 the first time too.
My a bit older GTX 690 (that's a dual GPU card) does 3700 khash/s with 3.0
(It produces "nonce does not validate on CPU" errors from time to time. It doesnt works with 3.5 and 5.0 my drivers might be a bit older)
My Radeon R290x standard does 2600 khash/s (sgminer)
Thank's to the devs of the x11 ccminer.

Now pls Nvidia .. where are your high performance GTX 800 maxwell cards!?
We need them NOW!
