Not only is Gainward the first company to have 1GB card on the market, the company can deliver this card at press time. We previewed the card yesterday, here.
Gainward has confirmed that it has both Golden sample and regular cards in stock and if you are ready to wait up to three days, you can get Golden sample at 650MHz core for €283+ shipping.
The key feature is that it will be the quietest card on the market and it will have a massive 1GB memory so you are certainly future proof.
You can order one and hope to get it shortly after Xmas here.
