3930k vs 4770k in X-plane 10 and FSX
Right now I have an i7-3930k and would like to know if it would be a waste of money to buy a 4770k and a Z87 motherboard next month and get rid of my 3930k. The only 2 games I have that are mostly CPU bound are FSX and X-plane 10 and I'm wondering if an i7-4770k would give me more than a 15% performance increase in these two games? As to people who are going to say to overclock my 3930k, same thing can be said about a 4770k, plus my 3930k is not a good overclocker, it won't run stable at 4.5Ghz at 1.3v with medium LLC, even when cores temps are under 80C, and something weird happened (not a BSOD, crash, or error messages) even at 4.2GHz at 1.28v without LLC, so I'm not sure even if 4.2GHz at 1.28v without LLC is stable on my 3930k as it stress tested for many hours without crashing or error messages but for that one weird thing that happened, so now I'm running my 3930k at stock settings. So how would an i7 4770k at 3.7Ghz turbo 4 cores compare to an i7-3930k at 3.5Ghz turbo 6 cores in these 2 games? I keep CPU power saving features turned off in the BIOS for performance reasons therefore turbo limited to all core turbo bin clocks and most likely would do the same if I had the i7-4770k as well.
