If they keep improving you might prefer the a770 for the extra vram as newer games seem to want more and more.
Are we at the point where 1080p is really demanding more than either 10 or 12 GB VRAM, or even 8GB VRAM? By the time that becomes a serious issue, if at all, these cards will be old.
It is getting close to a 6700 xt in some titles now.
That seems implausible. The 6700 XT has, overall testing based on the
hierarchy chart, a 25-30% lead over the A770 at 1080p, about 19% at 1440p, and 10% at 4K.
I suppose there might be a few outlier titles where the A770 might have a smaller gap than that, sure. Possible. Which games are "close"?
Regardless of that, though, why pay the same price for lesser performance across the board?
