Would this be a noticeable difference at 4k against a 980ti?
New driver with yet more decent gains in some titles.
The 980 Ti is still a strong performer - my niece was happily using a Titan (the 12 GB 980 Ti) at 1080p or 1200p until a week or so ago when I upgraded her to a 2080 Ti.
But the A770 has 16 GB VRAM. In more modern games like Horizon Zero Dawn I can bench at 4k on medium settings and get 50-60 fps. I've not tried the latest games.
Still a brilliant card from 8 years ago!
I bet that was a nice jump?
