Is this decent build?

If you want an AMD CPU, you'd probably be better off getting an FX-6300 and getting a Radeon 7950 or at least a Radeon 7870. The FX-8350 isn't worth sacrificing a much faster graphics card.

yeah that processor is a bit overkill, but i can get it for almost the same price as a FX-8320.

That doesn't matter if it still comes at the cost of a weaker graphics card. You would be better off getting a cheaper CPU and/or going cheaper in some other components (if not both) because there's no good reason to have a mere Radeon 7850 in a $1000 gaming build. That's what you might put in a $500-700 build, but in a $1000 build? It's basically just paying more money for about the same performance, IE not worth it.

Really, an FX-6300 would be a better CPU for your build because of the extra budget allowance it leaves to the graphics while having similar gaming performance to the FX-8350.

I think i will lower some cost on the CPU, I'll check out the 6300 also what would be the Intel alternative? also you said: and/or going cheaper in some other components (if not both). On which components could I go cheaper?
