Sapphire X800 XL Video Card -
The X800 XL is a full 4 quad pixel pipeline design (16 pipelines) with 6 vertex shaders running at 400 MHz core. The memory is on a 256 bit bus and is specified to utilize 256 MB of memory running at 490 MHz DDR (980 MHz effective). The overall specifications indicate that it should be a GeForce 6800 GT killer, but in testing it appears as though the NV40 architecture is a bit faster per clock than the corresponding ATI products.
