Ugh, that shit is idiotic and all the media sites downplaying the resolution differences are idiots. 720p Vs. 1080p in a game isnight and daywhen you actually play them on a HDTV screen. Easiest way to see this is to just hook up your PC to your TV and play with different resolution settings. Yeah, it's harder to tell the difference in shitty ass web videos, but in practice the difference is readily apparent.
Hell, you don't even need to hook up your PC to your TV, just do it on your monitor. There's no PC gamer on earth that would choose 720p over 1080p and for good reason.
