The chip is clocked at 626MHz core with 2000MHz memory and it will be priced at 800. The card should be available shortly and in Europe the company offers 10 years limited warranty. If you buy this card in the States you can count on lifetime warranty.
The card is tested at 626MHz and can work rock stable but this is not the last stop for overclockers. You should be able to clock it even faster. A chap called Vince Lucido set the 3DMark 2006 world record at over 24,000 points with a pair of EVGA 8800GTXes and an EVGA 680i motherboard, so anything is possible.
This is how the card looks.
