Could be something to it. Of course not the silly smaller bit bus or less physical vram arguments, but with the way the 970 handles vram once it approaches the 3.5gb mark. Its picked up steam at other forums and ManuelG a few hours ago said they are looking into it. A German programmer (Nai) has made a small program that benchmarks vram performance and we can see the 970 mem bandwidth tanking around the 3.3gb vs the 980: http://www.guru3d.com/news-story/does-the-geforce-gtx-970-have-a-memory-allocation-bug.html I'm not concerned because no game has let me down in performance (yet), dont play Skyrim with ultra texture packs or use exagerrated AA settings in games. Benchmark also seems to affect 780ti at last couple hundred mb of its 3gb vram as well (according to a 780ti owner who ran it).
