Looks pretty impressive and despite being an overclocked model has lower peak power consumption than a slower clocked referance HD4890 card:

The card is also very near to the GTX275 in idle power consumption and at 1920x1200 seems to be faster than the GTX275. It is a tad pricey at around £170 though. If it were around £150 to £160 though the lower power consumption,factory overclock and better cooler would make this a great card for the price.
