I'm going to be using a two way sli with geforce gigabyte 770 gpu I need a good motherboard preferable blue but will go with anything I want it to have 4 ram slots also even tho I will only be using two of them for now for under 300$ and was thinking an i7 4770k or i5 4670k pc will be used for gaming and internet browsing and watching movies online everywhere I read it goes either way on those two cpu so some info on why to choose one over the other would be nice
