well i went ahead and got a 660.
priced match using amazon.
came out to $226 after tax. might be saving more if i bought later, but i don't like my display scaring me for a month longer, plus it includes metro last light so it isn't so bad. i remember the last generation included duke nukem forever, so sad....
no problems so far.... but damn my tower was dusty inside. went over the cpu heat sink with a tooth pick. the gpu was relatively clean though, so i'm not sure if that had anything to do with anything.
