Found this collection of charts that shows a bit more than the raw FPS performance on cards, it has less publicized info such as power draws(idle and load) and heat generation (idle and load) and puts it all together in a selection comparison table.
Those were the factors i was more interested in since after advice and research i wouldn't get up to max settings anyway.
Very good for the non-enthusiast who just want to upgrade without the research hassle.
