Hm, dont know really, but my thoughts are, cos it has +25MHz CC, so you get 425/1100 out of the box. Second, Asus firm is leet, and I say you pay some money just for Asus name. And you get not-so-little stuff in.
And here is what I know:
- The card doesnt take extra PCI slot, which many of Ultras do
- Asus has leet cooling on 6800 series, atleast my 6800'GT'.
- Cooling is also damn silent, you can adjust fan rpm etc
- One of best good looking ever
