How much of a performance increase will Haswell E and DDR4 be?

[Pavel Pokidaylo]

Hi. I would like to know if the new Haswell E CPUs will give a big increase in performance over my i5 4670k.

Also my RAM is Gskill Ripjaw 1600. Would the new DDR4 RAM help much or not really?

Until they come out and are reviewed no one knows.
All we can do is guess.
