This is clearly an nVidia ad discuised...of course it's not just a baloon reminding you that you DO NOT have SLI, it also links to there SLI advertising page for "help" and "more information". Simply a cleverly slipped in advertisment that will stump millions...kinda makes me sad to be "spammed" by nVidia like that...although they do offer a fix for it, most won't find it or take the time to mess with getting it off...
