The performance is a lot better when you compare Nvidia to AMD GPU's around the same price point. However all of the problems that occur with the Nvida GPU's are not even worth the performance increase. From screen tearing to flickering, to random FPS drops for no apparent reason. Did I love the 20 FPS increase when overclocked on my GTX 660 compared to my 7870? Like an true gamer, of course! But at the end of the day, Nvidia really needs to step up their driver performance. No matter what I did, the problems persisted. As soon as I switched back to my 7870 all was well. Get your shit together Nvidia!
