Well, been pleasantly surprised with my 980ti's performance in the in-game benchmarks for the games I'm intending to play next.
Even at stock, I'm getting 63fps average in Shadow of War's benchmark with textures on high, everything else at ultra and TAA, and 65fps in Rise of the Tomb Raider with FXAA and everything but foliage on high.
That is better than I'd expected.
I've also been able to achieve a 20% overclock to boost clocks and a 300MHz memory overclock, which combine to give almost exactly a 14% increase in fps for both benchmarks (to 72fps and 75fps respectively).
I'm assuming (hoping) that these bench scores are reflective of what I can expect in actual gameplay?
And also hoping that Assassin's Creed: Origins isn't too much more demanding than these two! If that's okay at fairly high settings too, any graphics upgrade can wait for a few months at least.
And, whoah, the benchmarks looked gorgeous at 3440x1440 on this screen! The sharpness, the colours, the vision-filling aspect ratio... I had been languishing on a 1080p TN monitor for far too long!
