This motherboard has the best onboard video of any on the market.
Check out toms review.
My brother has built 2 of these for HTPC. Very happy customers.
You can add another video card if you wish and still use the onboard to create cross-fire set up. If you arent a hard core gamer I think this set-up should do everything you would want it to.
Wait.. one last thing. The black edition does not come with a cooling device so you will have to purchase one.
