So as you can tell I have 2 questions. The first is memory speed I saw some on sale on amazon with high speeds, and I plan on using the integrated graphics on the I5-4670k, but then get a 770, so should i get high speed ram (2133 mhz) or slower (1600-1866 mhz)? For my second question I want to know if getting ram that is "optimized for fourth gen cpu's" make a difference to regular ram. Here are some options I was thinking of.
