What exactly are you going to be using this PC for? Games? Office work? Standard home PC stuff? I assume this
is the case you've chosen.
If this is going to be a home theater PC or one designed for anything other than encoding, gaming, or crunching formulas, an AMD APU based system would work. If you're doing anything else, you may want a higher-end CPU from the FX line. If you're gaming, you will want that plus a good graphics card.
As for the hardware itself, its workable, but not really that great for high performance applications. I would consider it more of an HTPC or mid range home PC needing a dedicated graphics card. In the graphics area, that PC isn't great, but better than an integrated GPU.
AMD has three paths open to you. Go old school and find an older Phenom II CPU, go new and get one of the FX CPU's, or go for the integrated graphics and get an APU. The Phenom II parts are older with a more traditional design and are quickly being phased out by AMD. These are becoming a little more difficult to find and they are designed for the AM3 socket, though they are backwards compatible with AM3+. The FX CPU's are new and are replacing the Phenom II's. These CPU's use a very different "Module" based design where two CPU cores are partially independent but share a few resources. These are designed for AM3+ sockets and AMD is developing future CPU's for AM3+. The Llano APU's are basically a Phenom II CPU and Radeon graphics card on one chip. This makes them perfect for many people as they get reasonable graphics performance without the need for a dedicated add-in graphics card. These are designed for socket FM1 and are not compatible with AM3/AM3+ sockets, they are also going to be replaced by the upcoming FM2 APU's where backwards compatibility is not known.
If you want to go Phenom II, keep what you've got but replace the motherboard with Asus M5A97 PRO 970
. This is a bit higher end and is compatible with AM3 and AM3+ CPU's should you later decide to upgrade. It is also larger and more spread out than the one you've chose. This is a good board for people who will not be using Crossfire or SLI.
If you want to go FX, keep the Asus motherboard I chose above. Alternatively, if you think you will want to use Crossfire or SLI, go for the ASUS Sabertooth 990FX
. The Sabertooth is designed for multiple graphics cards and is designed for gamers who overclock and push their PC's. You can pair that with the AMD FX-4 4100 Black Edition 4 Core 3.6Ghz
, AMD FX-6 6100 Black Edition 6 Core 3.3Ghz
, or the AMD Bulldozer FX-8 8120 3.1Ghz
If you want to go the APU route, the AMD Llano A8-3850 2.90GHz
APU paired with the Gigabyte GA-A75-D3H A75
would be good. You can still use a dedicated add-in graphics card, but if you are going to do that, it would make more sense to go Phenom II or FX. The graphics on this APU is similar to that of a Radeon 6550.
Unless you're overclocking, you don't need RAM that fast, in fact, you need to go and specifically tell your motherboard to operate your RAM at overclock speeds to get maximum benefit out of that RAM. You can get the Corsair 8GB (2x4GB) DDR3 1600MHz
