kingadamdawgFor the best and most stable performance you should where possible purchase a CPU and Ram that have been tested and approved by the motherboard manufacturer, this is referred to as the QVL ( qualified vendors list ) understand though that there are too many products released for them all to be tested so other hardware will be compatible but not proven to be.
Couple of other pointers for you that will save you cash but still provide the gaming performance that you require.
Unless you intend using the computer for rendering videos, professional CAD or 3D work you do not need an 8 core AMD CPU or 16GB of Ram as you will not use their capabilities, consider the i5 3570k CPU and 2 X 4GB sticks of Ram as this is all you need for quality gaming.
The rest of the items are very good but I would change the HDD for the 64MB Cache version which is actually less expensive http://www.amazon.co.../?tag=pcpapi-20
Other points are that there is no operating system listed so you may need to add circa $100 for Windows 7 64-bit to your budget, if you are able to save enough cash by changing some parts consider adding an SSD for your OS to speed up your boot times and finally remember that you should not choose a PSU until all other hardware is selected and confirmed as available and then use a PSU calculator for guidance, an example http://images10.newe...tage-Calculator
If you tell us your maximum budget we can provide an alternative list of parts for you to consider.
