its not looking good as far as the performance against current cards go. But the price should be around $300-350. They're saying its basically an overclocked 8800GTS.
With EVGA brand GPU's you if you buy a new card and you want to upgrade and 90 days hasn't passed you can send them the card you bought pay the difference between it and the card you want and they will send you the new card. I'm pretty sure thats how it all works.
