Would say keep it as is, 25mh/s average on <110 Watt is a very decent result for that old card.

We were getting 32 mhs with the good old 110 W. Dag epoch increased, mhs started to drop on nvdia cards, no solution was found.
Yea i know, did >34mh/s on ETC, but not worth for me to mine, as it had still less Payout over ETH.
And also my suffer has a found a end.
