We haven't seen your box since the video you posted! What ever happened to it?
Gaming is more than possible on linux, and honestly forcing skyrim through OpenGL makes it faster and, in my opinion, better, but thats besides the point.
Gaming is possible, video editing has kdenlive, lightworks, and nonesuch editors, coding..... Do I have to say anything?
Everything is possible and you seemed excited about it. I thought you would have more vids on video editing or have the community make videos to put up. Even tutorials for distributed computing or how to use WINE for heavy gaming!
