Is this the best value gaming PC available right now ?

I'd lower the mobo to a 970 ( still with good features ) and add in a cooler instead. Higher gaming performance since you can OC your CPU now :

Might downgrade the vga to a Powercolor 7870 xt V2, too, but then that card doesn't have a good cooling system.

Yes, also I can upgrade CPU in the future when Steamroller comes out. I have other parts, need only these 5 parts. Thanks
