I am going to upgrade my i7 4770k to a i7 4790k . my current motherboard is a aus z87 rog maximus vi hero . I have had no luck with overclocking my i7 4770k with my asus z87 rog hero . I can only get my i7 4770k stable @ 4.3ghz . the i7 4790k has a stock turbo frequency of 4.4ghz that all ready beats my overclocked i7 4770k . I can get a good deal on the asus z97 pro . would I be able to get more out of my i7 4790k if I were to upgrade my motherboard to a asus z97 pro ? or would going form a asus z87 rog hero to a asus z97 pro be a downgrade ?
