i7-4770S vs i5-4690K

[pavars]

I plan on mostly gaming, and I wanted to OC the i5 as well, but I can get i7 for 10 eur cheaper but only the S version, so in overall performance which one should I go for?
Here's the initial specs but it's not yet decided:
CPU: Intel Core i5-4690K
Cooler: Phanteks PH-TC12DX
GPU: GIGABYTE GV-R928XOC-3GD (rev 3.0)
Motherboard: Asus Z97 PRO Gamer
PSU: FSP700-50ARN 88+
RAM: G.Skill DIMM 8 GB DDR3-1866 Kit Sniper Series
Case: NZXT Lexa S

I have a chance to get some of the components cheaper (but as far as I understand, used for a little while, some parts still have warranty)

i7-4770S
Gigabyte GA-Z97X-GAMING 3
ASUS Radeon R9 280X
Corsair CX750M
Kingston HyperX Predator 2666MHz DDR3 8GB
Arctic Freezer i30 CO

well, the mobo is a bit weaker than what I intended but since I won't be able to OC, then it should be good enough, probably gonna grab this PSU and I would take the GPU but as far as I read Asus has the most artifacting problems of them all...

Which parts are worth taking and putting in my gaming rig?

Definitely the i5! it gives you more options imo

since the i7 and i5 are slightly of same performance and the i7 is cheaper ,i7 would be the best option if you are not overclocking the chip , but overclocking the i5 would make it more powerful
i7 = more threads and cache
i5 vs i7

Go with the 4690k build

- Can be overclocked
- Has a better PSU
- i7 with HT doesn't benefit gaming much unless you go crossfire or SLI

i7 4770s base clock is 3.1ghz. An overclocked 4690k would be faster in any game. Like posto above said, HT isnt going to help in games while higher core clock will.

I'm thinking to pick RAM from the other build if I OC then it should work better (I mean higher clockrates), maybe GPU and are you sure about the PSU?
I can save a few bucks if I pick some of the items from the other build (since I will be picking other parts individually from online retailers)
