1600mhz vs 1866mhz with integrated graphics

[someguy1231]

My specs:

A-10 6800k quad-core 4.1 ghz
8GB 1600mhz RAM
Radeon 8670D integrated GPU

After much research on this site and others, I've concluded my biggest bottleneck is my RAM speed, since I'm using an integrated GPU rather than a discrete GPU (ie video card). RAM speed is apparently much more significant for iGPUs, so I'm wondering how much of a performance increase I can expect if I replace my 8GB of 1600mhz RAM with 1866mhz of the same amount (my MOBO doesn't support any higher speeds, unfortunately).

Let's use Skyrim as my benchmark. On High Settings I generally get 25-35 FPS. What boost should I expect?

extremely minor.
IGPUs aren't meant to be gamed with.
You'd be better off getting even a $60-80 GPU.
