You can switch to the Blu-Ray and 2TB posted on page 1, add peripherals and card reader, then get ready to click a few buttons and join the 4Ghz club without breaking a sweat. You will also be able to add a second GPU (and a bunch of other stuff in the future) with this mobo if a 6950 isn't fast enough.
