How did you get around ghosting lag issue? Did you disable overclocking? If so, how?
Pretty sure the Rampage III is a motherboard, not a video card?
What do you mean by ghosting lag issue? you mean where someone is there attacking you but you cant see them?
Also, if you dont know how to disable overclocking your graphics card, chances are its not overclocked(unless it was custom built via a website and they did it for you). and if it is, i recommend just googling how to overclock your pc. Its not exactly something you wanna fuck around with without proper knowledge, as you can fuck up your computer doing it.
