Have a look at your Gpu power usage and core usage while in game, I had an issue a while back where it would only use like 50% power resulting in poor fps.
My SC's are at 1500mhz for gaming but that's with a 1.255v bios. Before that at 1.23 they would do about 1430-1440.
Witcher 3 for me is the poorest SLI profiled game. 70- 80% usage on gpu1 and 80-90 on gpu2. I've seen it drop to 90fps on occasion (still using 80% GPu usage -.-), ultra settings minus Hairworks.
Compare that with mad max I've been playing recently. Every setting on and maxed out at 120fps 1440p. Rock solid 120hz with a peak of about 80% on each GPU.
