Well, it looks like the Radeon X1900 XTX has earned the title of the fastest single video card known to man. Oddly, though, two Radeon X1900 cards in a CrossFire config can't claim the title of the fastest two video cards known to man. The CrossFire card's marginally slower clock speeds, along with a tendency not to scale quite as well as SLI overall, leave that title with NVIDIA's GeForce 7800 GTX cards in SLI. Still, the Radeon X1900 series is quite an accomplishment. If they are indeed widely available for sale as planned, they should be very solid choices for those looking to spend an insane amount of money on a graphics card, especially since GeForce 7800 GTX 512 cards have become scarce and expensive since their launch.
