790GX is slightly overpriced for simply being a 780G with overclocked IGP and SB750 southbridge. these things are all great if you're a phenom overclocker, but if all you want is a low-frequency K8, there is no need throwing the extra $30 at a motherboard. if 1080p playback is a requirement of yours, then presumably you have a large LCD you're using this system with. spend money making the system silent, and get the biggest hard drive you can. you'd be surprised how fast a terabyte is filled by 1080p content.
