It stung a little, as I'm running a 1680 x 1050 monitor.. but eh, this is the first time that I've ever owned a video card that wasn't a few generations old.
I have a 1680x1050 as my main computer monitor, but I also have a 1080p TV right next to it when I want to game. Don't worry about the resolution, it's not overkill with more intense games to be quite honest (Witcher 2, BF3).
Enjoy it, I know it stings right now, but you'll never look back!
