Are these parts compatible?

Solution
My best advice is to get the 4590 + H97 mobo which allows you to step up to a R9 280x for the same price.

Is this for gaming? Care for more advice?
 
Yeah, it's for gaming. I wouldn't mind taking advice, but I believe I have everything in place. If one of the suggestions would be about the RAM, (dividing it,) I'm planning to upgrade it in the future. Other than that, sure, I'll take any advice. Thanks.

Overclocking is over-rated and will not even come close to making up the difference that getting the 280x over the 270x would make. This is far superior in gaming.
