RAM Capacity or RAM Speed for APU?

[Claszureme]

Well, my A10-7850K is using 4GB KiNgston RAM 1600 CL11 right now, And I'm planning to buy a 8gb G. Skill(4x2) 2133Mhz CL9 RAM, but I want to save some budget a lil it. So my 2nd option is to buy 8GB G.Skill(4x2) but "1866"Mhz CL9. so what ram should I buy? and of course, faster ram or more capacity for an APU?

If you are using the GPU on the APU you will benefit from faster ram for graphics.
