I received my new 13.3" Optimus today, and I have just tested Skyrim. The screen is great. It's really comfortable for gaming and work. With the 1080p resolution on the matte IPS screen 3D gaming is really great and the size of the screen is not an issue at all.
I would say it really depends on you, I have a 13" laptop and find it very difficult to play games on it due to the size of the screen but for office and work it is fine.
