Bjorn3D.com checks out PowerColor X800 GT and overclocks the core to a wopphing 551MHz - well above default Radeon X850 XT PE. I have drawn plenty of facts from testing ATI's latest VPU, RADEON X800 GT. PowerColor X800 GT is a beast in its own class. Thanks to very high core and memory clocks the performance of an 8 pipeline card is as good as it will ever get. We show you how to bump a 475 MHz core beyond X850 XT PE's with just few minutes resulting in a massive 551 MHz overclock. The beauty of RADEON X800 GT is its R480 core. Though cut down to 8 pixel pipelines, you get great performance at a reasonable price. You won't get a better deal for $159 USD (256 MB version), but if you think that's too much consider a 128 MB model for $139 USD
