My current card is a ATI Radeon HD 4500 series.
I play a ton of games (Far Cry, Assassins Creed, Skyrim, Fallout, etc), but currently all on their lowest settings. Rome II is the big one I am getting ready for haha. So for what games and resolution, I want to simply say 'the best I can'.
I live in Canada.
