which cpu is better

Solution
For gaming stick with i5 4670k or 4690k.

R9 280x is a solid card.

For this setup 650W is plenty. Better get HX 650 or Seasonic/XFX series 650W 80+ PSU.

Apparently no need to go for i7 if you are overclocking and gaming only.

If you are going to OC, get the i5, as it has an unlocked multiplier. If not OC'ing, the i7 will win, hands down. However if you can , get an unlocked i7 4790K. (maybe a bigger PSU too)
