More performance, less price.

Thanks. but is it worth degrading the 16gb ram to 8gb?

Yes. Almost no applications use 16GB of ram. APUs gain alot more power from speed of the ram. So you get less ram, but much faster ram. This is important for an APU build. Also the 6670 crossfires with the onboard graphics.
