I'm a little wary of the statement that "the majority agree with me" when the thread is driven mostly by 3, and two of them are disagreeing.. . I use a 3080, and I believe that 10gb is enough for it - It certainly is for me.
Would I have liked more on it? The answer to "would you like more" is always of course, but you have to deal with what is there, I knew what I'd purchased, and was delighted. There's certainly a discussion to be had on whether more could have been offered, but I reckon that 10gb is plenty for the next few years except for some potential outliers, where a few settings can be turned down and off you go. I think that more and more games will be ported from console rather than developed for pc, and a VRAM overhead will allow for quicker (lazier, or deadlie driven) coding, which may be the bigger impact on whether ram is enough. Is it enough for the image? Yes. Is it enough for the game? Possibly not. . Someone made that point previously, but it makes sense.
Works against AMD too, currently Ray tracing will need to be turned down or off in certain cases. No one card runs everything at full power all the time, it has always been thus. You just decide what's better for you, and if 10gb isn't enough, there are other options which also can't be purchased right now.
Admittedly tongue in cheek, but is a 12gb 3080 enough? It is still absolutely fine, and will run nearly everything.... But it isn't 16gb, is it? And is 16gb enough, when you can get a 24gb 3090?
