Beyond3D takes a look at ATI's X800 series with two GTO products from Sapphire; the Sapphire Radeon X800 GTO and X800 GTO Ultimate Edition

Those of you who are familiar with previous designs from Sapphire's
range of Ultimate Edition boards will find no surprises here - just like these previous efforts, the X800 GTO Ultimate Edition features a hefty (although
admittedly less so than previous Ultimate Edition solutions) heat-pipe cooling arrangement which transfers heat away from the core to the heatsink on the top of the board. The obvious advantage of such a mechanism is that it requires no fans to cool the device, and as such offers silent running for anyone looking to build a silent or near-silent PC while still requiring a respectable amount of 3D gaming performance.
