Here's the review on 3080ti remastered mode on 2k resolution. IF YOU ARE FULL TIME STREAMER, using 3080ti on Twich studio beta will auto stream 1440p. Even the max setting is 1080p. Example : https://www.twitch.tv/videos/1053040123
not sure about 3070ti. But 3080ti is almost like 3090. and i'm more surprise you can stream 1440p with Twitch studio beta even the max setting is 1080p. I was thinking im streaming at 1080p , and after i watch the replay, it shows 1440p ( video is so clear without any stuttering ) . Example : https://www.twitch.tv/videos/1053040123 .
Full time streamer should consider this card as a good long run for at least few years to come.
