Also any estimates on the wattage I should be looking at? The calculators have been saying 450w~ but that can't be right.
If all your going to play is star craft 2, then that is probably more graphics card then you need. However, if you think you might want to play any of the newer big ticket games, especially first person shooters, you are going to want the power. I'm of the mindset that getting more then you need now will make your system last longer before needing an upgrade, so you may want to take that into consideration.
As far as a power supply goes, you probably would be safe running that setup on a 500W power supply. If you wanted some headroom to add another graphics card down the road, I would recommend going higher. The biggest thing about power supplies is to read up and get a good quality unit. If a power supply dies, it can take other components with it. Even if a power supply doesn't die, you can still have performance issues if it isn't giving good quality power to the components.
Also, most of today's graphics cards require two PCIe power connectors, so you will need to make sure that you have that in a power supply. The 6950 requires two 6 pin power connectors. You probably would be fine with something like an Antec Earthwatts 650W power supply (http://www.newegg.com/Product/Produc...82E16817371015
), but for a little bit more, corsair makes some great power supplies that offer some more advantages over the Antec unit. The Corsair TX650 (http://www.newegg.com/Product/Produc...82E16817139005
) has 2 more SATA connectors and 2 more molex (peripheral) connectors. And their warranty is 5 years instead of 3 years. The TX750 (http://www.newegg.com/Product/Produc...82E16817139006
) is basically the same as the TX650 except it has two more PCIe connectors allowing you to run a second graphics card at some point in the future if you decide to. Also, the Corsair power supplies offer a single 12v rail versus 3 with the Antec. A single rail is generally better, so Corsair has an advantage there.
Sometimes picking a power supply can be the hardest part of the build, at least for me. The main things to look out for are getting a good quality unit Corsair, SeaSonic, Antec, and PC Power & Cooling are some generally good brands that come to the top of my head. There are other good units out there too, but these are generally considered some of the better brands. After that, look to make sure that there are enough connectors for everything, and make sure that the 12v rail has enough amperage to supply power to everything.
