The 5775c will win some and lose some. It's slightly faster per clock and has L4 cache which really helps in some cases. It's also a lot more power efficient. Overall, the 4790K will probably perform better on average, but if given choice between the two I'd take the 5775c personally.

The 5.0GHz 4790K is more powerful.

The 5775C is a 5th gen intel Core. It comes with Intel® Iris™ Pro Graphics 6200, and as far as I know, it isn't overclockeable. You'll stuck up to 3.3GHz and with turbo to 3.7GHz.

Basically, if you pretend to game, just go with the 4790K and a GPU.

Are you sure?

No, it has an unlocked multiplier, so it is overclock-able.

The 5775C tends not to overclock as well as the 4790k, so that can be a detriment if you have a dedicated graphics card. On the other hand the 5775C does get L4 cache which can be helpful in some situations and might give it an edge in some games assuming similar clockspeeds. If you have a dedicated graphics card it's a toss up, with the 4790k usually being the cheaper option.

Sorry my bad, yes it is overclockable, I was thinking on the 5775R.

Oh, I heard that once you overclock the 5775C to around 4.2 GHz, you'd get better performance than even a higher-clocked 6700k due to its L4 cache.

It depends on the application and the difference isn't huge when the L4 cache does help, certainly it's not worth the large premium that the 5775C goes for. If you have the money for the 5775C, then you can probably also afford to go to the X99 platform and get a 5820k or 6800k which have two additional cores which is going to be more helpful than L4 cache.
