Oh yeah, baby! Dell got called out on this little bit of fraudulent advertising, by Reddit readers and apologized for this "mistake". Oh yeah, so intentionally blurring a picture, posting it in an advert to state a lie in order to sell expensive graphics cards was a genuine "mistake" was it? Dell's "apology": Don't you feel reassured now? Moral of the story: don't be clueless about what you're buying and you won't be fooled. More details at PC Pro here and here.
