The folks at Sapphire are claiming their new Toxic X1950 XTX is the fastest card on the planet. So fast that it comes with its own built-in liquid-cooling (which as you can tell will take up an extra slot in addition to the PCI-Express slot occupied by the card). Both the single-card version and the CrossFire Edition of the card can be overclocked to 695MHz (from 650MHz). They come with either 256 or 512MB of GDDR4 memory and support dual-link DVI at resolutions of up to 2650x1600. Better start saving now as the cards will go on sale next week for about $549 bones.
