Hahaha yup. I'm a dad in Canada so all I do is yell "close the door"
My undervolt saves about 50 Watts and that's 50 Watts for every minute gaming do it does add up a bit over time and it's about 5-7% less performance.
About overclocking. My card performs as good or better in some games then a 3070fe stock so it does add quite a bit.
I undervolt my 3060ti ftw3 ultra as well. I am concerned about temperatures and the needed speed isn't needed, especially after having 3 gpus die on me after 2 years (8800gts, 9800gt, and ati 7870) With shortages in cards coupled with miners and scalpers, its not something i want to deal with.
I have a 1080p display but still use 1440p dsr and it downsamples to 1080p, which makes some games really sharp.
I undervolt as the ftw3 card uses a ton more watts over stock founders cards. The fe is rated 200watts yet my 3060ti gets up to 230+ in max load, with almost 2100mhz range , kinda nuts for a card that base clock is rated at 1800 MHz (1665 for founders).
I undervolt due to temp concerns. In cyberpunk i was getting mid to upper 70c's which was making my office air hot. Not to mention the stress on the card. Some other games like city builders i was getting 200+fps way overboard. I cap my fps for that. I set the power to 95% (instead of 100) and the gpu temp throttling at 78 instead of the 85 it sets as standard. Lowering the power wattage down 5% , I don't notice any frame loss. Still see wattage well above 200w, but temps never get past 72-74 now. In games like Elden Ring with capped fps, I get locked 60fps and temps in the 60s. Shows gpu load at around 60-80%. Haven't had a game I couldn't max yet.
The 2060 I had prior was awesome too. It wasn't as fast with RTX though, and I couldn't pass up on a step up program with a $80 price tag. Glad I did as the $450 I paid for my card has been selling for 1100+ due to shortages. I kept my old 1650super and 1060 as backups, even though I could sell them and make a ton, its sad even if I sold them I still couldn't replace the 3060ti.
I really hope the shortages clear up soon and mining gets banned. (yeah i said it. As a gamer, fuck bit coin mining. You assholes are ruining it for budget concious gamers. You destroyed the gaming sphere. I won't spend over $500 for a gpu and 400 was pushing it. New comers into pc gaming are fucked. A new 60 series card used to be $200 , now its $1k. Insanity. Shit you can't even get ultra low office cards anymore. Cards that would sell for $80 and barely push frames are now $300.
