I have a Gigabyte 1050ti G1 Gaming OC card and I'm doing 12.5 to 12.9 Mh/s with Phoenix miner on eth mining. Is this okay or is it easy to pull some more out of it?

I've only used the easy setting in advanced OC settings.

I'm running the card on an old Asus p5ql pro main board with a e6850 cpu. Don't know if this is limiting things?

Should the hash rates be better with claymore mining?

Oh and how long can I expect the card to life when mining everyday with a bit of OC?

Thanks a lot!
