do 7970 cfx. Why are you getting a sound card. I don't really think you need it. Also I would get a 2x4gb ram. I would look at getting a gigabyte, asrock, or msi board.
im getting 16gb because i will be doing some moderate editing and im getting a sound card because onboard audio sucks and i want the best performance out of my headsets. Im just wondering if all the parts will fit on the motherboard and if the wattage is enough
