@5tu88sy: 2x 780's. Same performance as a 1080 when overclocked, but SLI scaling is a pretty big issue as a bunch of games are not supporting SLI, or not supporting it well. Plus the cards kinda turn into a loud furnace running overclocked at max load..
The 1080 Ti would give me more of an excuse to get off SLI, but a single one is still not enough to drive modern games on a 3440x1440 display at 60+ FPS (and those displays are 100+Hz).
@analgrin: In non-games there is a performance loss.. but I guess that should be expected since it's a gaming card over a prosumer one.
In games, the increased memory speed is the only thing improving the framerate. If a game doesn't scale based on memory frequency, performance will be lower than the Titan. Also, it would have much better performance if they didn't cut the memory bandwidth.. boggles my mind why they did that. Didn't want to outclass the Titan that much? *sigh*
But yes, it's at most 5% better in games that do scale with memory speed; 1-2 FPS. Hardly anything worth writing home about.
Too bad it took them 9 months to release the goddamn thing. I needed it back when the 1080 came out (was not an upgrade over my 2x 780's, but SLI is a problem with lack of support), but of course NVIDIA had no reason to do so since there was zero competition and it would just remove sales of the Titan.
At this rate it might just be better to wait until Volta.. unless that actually comes out in 2018.
