It depends what you plan to use this machine for and when you'd plan on upgrading. I personally went with a less expensive/powerful video card, though yours will likely last a bit longer. Many will disagree, but I don't really see the point in paying for the Intel SSD if its only purpose is WoW. You can get a cheaper, and just as effective SSD for now and then get a nice SLC version in a couple years when they're significantly cheaper.

You have a lot of nice options there, but only 6GB of RAM. I'd upgrade to 12GB... if that means downgrading the video card or SSD, then I'd do it.
