I'm aware that both of these are old as hell and basically the same thing. I have my 870 overclocked already and was wondering if swapping to the 875k would give even slightly better performance after overclocking.
Right now its clocked at 3.52 GHz, I think the ram is clocked at 1562 mhz.
I know that upgrading is the best route but I don't have much money right now
