Starcraft 2 is running extremely well right now, but I haven't put it to the full test of a 4v4 multiplayer map. Hopefully I will do so later this weekend. Unfortunately, Skyrim did not fare as well. I am at the point that I will need to uninstall all of my mods and then reinstall them one at a time. Currently, I keep getting a render error, which suggests to me that the game is not correctly reading my video card, or maybe a file got lost when I had to reinstall Windows. One way or the other, I think that a complete reinstall is my best solution. I just don't look forward to the time that is going to take.
That said, this was one of the smoother reinstall/upgrades that I've gone through. Unlike the last couple that I've done, there was almost no swearing involved.
Also, I have never had a computer run this quickly before. Aside from the Skyrim issue, I couldn't be happier with this computer.
