Help me with a gaming PC build

[Axk29]

So I'm thinking of getting a 4670k or a 4770k as my processor. a 270x or a 760. I'm not sure which one should I get. I'm also quite unsure about the other components. I'm not an expert at the other parts myself I've only began to grasp the understanding of how components work. I need help regarding the rest of the build.
As long as I have 4670k or 4770k and a 270x or 760 whichever you guys think is better. I'm good with it. Don't include the OS and monitor. I'll got those covered. Thank you guys ). As cheap as possible plz

should have given us a budget. if you got some to spare, consider either a 770 (if you got a 1080p monitor), a 120GB SSD or a case more to your taste if you prefer that. getting a 4770K should be the least of your priorities here in terms of gaming performance unless you're extremely fine with everything else.
