I just can't answer it, as I can't see the future. Both are great cards & I think you'll have a lot of fun gaming for a long time on either.crazy I put in a max of £900 and this didn't come up just now ha! Well yeah I'd definitely buy that at that price as I was going to pay that for a msi 3080 10gb elsewhere... so is the 12gb still not worth it in your opinion vs a 16gb 6800xt?
Especially if you stop following the graphics card market as soon as you buy & just enjoy turning all games up to (near) max.
If I were buying today at £639 for the 6800xt vs £830 for 3080 12GB, for strictly gaming, I think I'd take the 6800XT & keep the change.
But the 3080 12GB wouldn't be a BAD buy, if I was comfortable spending the money.
