UPDATE - July 12, 2008: The card was supposed to be available on July 11 but according to the webshop the GeForce GTX 280 Extreme is still not available..
Computer enthusiasts who absolutely want the fastest single-GPU graphics card will be glad to hear that you can buy something that's even faster than most overclocked GeForce GTX 280 cards. Overclockers.co.uk is listing a GeForce GTX 280 Extreme graphics card from Leadtek on its website and this part is a lot faster than every other GT200 card, even the watercooled EVGA GeForce GTX 280 is no match for this aircooled Leadtek card.
The Leadtek GeForce GTX 280 Extreme 1GB has a 738MHz core, 1666MHz shaders and 2520MHz memory clock. Regular GTX 280 cards have a 602MHz core, 1296MHz shaders and 2214MHz memory.
The card will be available on Friday, July 11 for £387.74 (incl. VAT) and has a 2-year warranty. The price is a bit higher than a standard GeForce GTX 280 but a lot cheaper than the price those overclocked EVGA cards are selling for.
