Okay so I'm building my first PC, and i do plan on doing a good amount of gaming(Skyrim, Bio-shock,bf3, etc...). My system, which is linked below, has AMD's Radeon HD 7770, graphics card and i wondering how well the card will do on Ubuntu On windows playing games like Skyrim, and bf3 can play on high/ultra(1920x1080) while keeping around 30/40 fps, will i see similiar fps on ubuntu? If anyone has had any experience with this card or similar amd cards feedback would be greatly appreciated, i really wouldn't want to resort to using windows for gaming as i would like to keep a cohesive desktop experience but is fps gaming on Ubuntu yet possible?
Thanks
