I have been out of the loop for a while and will be upgrading in the next few months. Part of that is the Mobo and RAM. Should I be looking at DDR4? I have only read one thing about it and it said there was no real use for it in gaming. More for industrial use. Is this accurate? If I go DDR3 is there any use in getting anything over 1600? What kind of CAS timings should I be looking at as well. Thanks.
