As the title says, I'm about to build my own computer, and I am having a hard time deciding which GPU is the best to get. I will be using a 21.5" 1080p monitor, and I plan on playing all kinds of games including Skyrim and ESO, League of Legends, WoW, Hitman Absolution, Battlefield 3 & 4, and Saints Row 3 & 4. A good mix of next gen and current gen games. I would like to get the best bang for my buck while maintaining playable framerates at higher settings. I will also point out that I plan on dual-booting Win8 and Ubuntu, so I'd like the card to have decent support for Linux drivers, which is why I am leaning toward Nvidia. I have heard they have great Linux support. Any advice would be appreciated!
