That doesn't matter if Dolphin isn't coded to use the latest version. Think like OpenGL. Your GPU can support the latest version of the API, say 4.3, but that's pretty useless if a program is coded to run OpenGL 2.1 code. Note this may not be the best example, since I don't have any experience coding OpenCL, but hopefully it's not too inaccurate :p The files under Source/Core/VideoCommon/Src/OpenCL/ simply aren't designed to take advantage of what the latest OpenCL versions offer.

That's because, as I said before, the OpenCL texture decoder is slower than the default one. It might perform at the same level (enough not to notice the difference anyway), but it's very unlikely to consistently improve performance

There's a high probability that the result is going to be the same even on a higher end GPU. I can confirm that OpenCL in Dolphin, as it currently is, does not visibly improve performance.

SSE3 is an x86 instruction set, i.e. it's specifically for CPUs. What do you mean by "a GPU that supports SSE3"?
