Im certain the x58 system will still be slower...even if you manage to find one at 4.5 ghz...
I am certain of that too. All the chips of that generation have a roof of working with only 1066 MHz DDR3. Anyway, the HC test, as i said, was not done properly with GTX1070 being the limiting factor and with AA used.
Digital Foundry gaming tests show what a big difference Core i7 8700K can provide vs. Core i7 7700K, since they use GTX1080 Ti and use no AA, which shows that Core i7 2600K would be totally demolished by Core i7 8700K. I was mostly shocked by Crysis 3 results - Core i7 8700K opens such a huge gap that you really begin to understand that Crysis 3 was so ahead of it's time in terms of technician prowess. In Crysis 3 Core i7 7700K beats Ryzen 7 1800X, so i thought that we have reached the performance roof of that Crytek engine, yet Core i7 8700K just wipes the floor with Core i7 7700K and even beats the 8 core Core i7 7820X! This is the first time in history Crysis 3 can be played at max settings/1080p at constant 144 Hz! Ye, only after 4 years. Just like only after 4 years you could finally max out the original Crysis with HD7970.
