That GTX280 is overclocked by 100MHz... That in itself is amazing considering the size of the chip
That being said, while it's does seem to be the fastest card in the test, it doesn't seem to be by any kind of large margin, and even loses out to the 3870 X2 in stalker, and often the 9800 GX2 in other tests, the OC edition actually consumes more power than the 3870 X2, 9800 GX2 and 2900 XT while under load. It's fast, but not 'I'd spend £400+ on one' fast.
