Looking to build a friend a pc soon. The thought crossed my mind that this would be a good time to upgrade while giving my friend a great deal on a excellent build. I would be overclocking the 5820 obviously and along with the ddr4, I feel this would be a good combo for my gtx 1080. Would this be a worthy upgrade? Would I see a dip in heavy single threaded applications such as arma 3? Thanks for any input.

You should be able to hit 4.5Ghz on the 5820k, so that removes the issue of single thread performance as both the 4770k and 5820k are Haswell architecture. (So they should have identical IPC)

I recently did pretty much the same upgrade - selling my 4770k to a friend to get a 6800k, and I've noticed better performance across the board. One unexpected effect of the upgrade was an FPS increase in BF4 multiplayer, as well as a few other titles.

Although the quad core i7's are more than adequate and are praised for their gaming performance, it appears I was actually being bottle-necked, as I noticed an increase of around 30 FPS. Which is interesting, considering my usage with the 4770k was never above 70% ingame...

At 4.5Ghz, it should be the same speed clock for clock in single threaded tasks.

Multi-threaded you would see a significant difference of course due to the extra threads.

4770k @ 4.5GHz with an H100i, so same speed as yours.

That's why I found the increase so interesting and hard to understand.

Although the 4 cores for gaming argument is strong, if you usually run a lot of background applications you will notice a major difference.

My friend said the same after jumping from his 4690k to my 4770k.

Just as an indication in Firestrike. I know its synthetic and in games you probably won't notice a whole lot between the two. Extra 2 cores could come in handy in future though. Longevity is anyone's guess if/when 5820k would still be relevant when games do eventually require/ benefit a 6 core cpu.

5820K + 1080

4770k + 1080

Majority of both CPUs there are overclocked 4.5+ with 5820K fairing better. If price isn't much different i would choose the 5820K for gaming and other stuff.

There isn't a massive jump in performance from DDR3 2666 to DDR4 2666 though, so I doubt its the RAM, and Z87 wasn't exactly sluggish or anything.

Anyway, whatever the cause, it's likely that OP would see a similar increase as he would also be upgrading from DDR3/ Z87 or Z97 to DDR4/X99.
