I did not even try the eth- enlargement pill from ogoditisagirl.

I don't feel so bad that I just today got around to trying out the ethlargement pill on two very different 1080s and all I can see is, "holy frijoles!" On a 2+ year old EVGA Founders Edition, Ethash went from a pathetic 21 MH/s to 30.5 MH/s and power consumption dropped about 40W. Next I tried it on a much newer Asus RoG Strix 1080 mining CryptoNight (not ideal, I know) and hashrate went from about 540 H/s to about 630 H/s.
However, trying to increase the memory clock rate by +100 caused the FE card to crash so hard I had to hit the reset button. So, be very, very careful with the overclocks while on the pill.
Yeah it's the business. I found with 1080tis I was previously overclocking mem +400 that +200 was enough to get mid-50MH/s.
