Gaming for example will see a moderate benefit, also socalled multimedia applications. Assuming its an exe compiled for it. But the benefit is that you can take existing SSE code and just recompile it for the AVX2 benefit and 256bit execution. So the work (and cost) from the developer side is basicly 0. So there is no excuse not to use it in all newer applications and games. AVX2 is radically revolutionary due to providing vector equivalents of every scalar instruction.
