I have seen this posted a lot and it is a bit of a misinterpretation.
IIRC it was an overclocked Toxic 280x gets close to a stock GTX 780. If we remember the GTX 780 is also an excellent overclocker this leaves quite a bit of distance between the two cards.
You can also make the same argument for the HD 7970 (rebadged as the 280X) my Asus Matrix Platinum 7970s can give the stock GTX 780s a run for their money.
Having said all that the Toxic 280X looks like a top notch card.
