It's that more powerful those extra cores and speeds and Vram 68C at the moment my cardI believe it. I think that was going to be my next upgrade but I'm good for now. I like my 3080 for now. I wonder why it runs hot than others, if the even higher cards are hotter or not?
It's not worth going from 3080 to 3090 anyway, going to a 5000 series would be a good ideal - Like me I want from 1660TI to an RTX 3090 LOL
