In my opinion AMD give you more bang for your buck. Intel will have higher performing parts but you pay more for them. If your main objective is gaming your GPU is going to be more important than you CPU unless you decide to go for an APU.
Check in with a Xeon E3 1230v3 from intel, same power of an i7 but at an i5 price point. I have one my self works great on almost any z87 mobo. I'm running a msi g45 z87 and it works amazingly, this thing flys. And for intel it's some what cheap. And it for sure knocks any amd 8 core out of the park.
And it does not over clock! There really is no need to, and it runs cool! Well it only hit 100 Celsius on stagnant air, and about 40 when I realized when the fan on the heat sync wasn't spinning... but these were both on full load!
How does it knock a sub $200 8 core out of the park when it costs $250 and has a lower passmark score? It doesn't even natively support 1866 memory. Also not having the option to overclock isn't a feature, what if he wants to overclock later on down the road?
