My 4 year old 28nm HD7970s have 2048 stream processors each (4096 total). And, they still run everything the way I set up for games (default AMD Radeon Settings, "ultimate" in game-settings, highest resolution downloadable textures when available, 0AA). Usually, one card is enough (2048 stream processors).
I want at least 4096 stream processors on a single 14nm GPU. So, I may wait -- now that I know the 14nm "big one" is not due until 2017. I may follow SkateZilla's plan and upgrade my FX9590 CPU first (at the end of 2016 -- at black Friday prices, I hope ). Anyhow, I'll "play it by ear" as the cards are released and test reports come out.
