First off, PowerColor's GameFX X800 GT 256MB is based on the R480 core, and as such it overclocks pretty well - we found that it was 20MHz faster than the fastest we could get either R423-based card to. However, the 2.0ns memory overclocked poorly in comparison to the other cards. The card is a solid Radeon X800 GT implementation with a nice cooling solution that should allow you to attain some reasonably good clock speed increases. You get a free game along with most of the required adapters - we'd hope that PowerColor will consider adding a second DVI to VGA adapter in to the bundle, as it's a missing link in an otherwise solid product.

Sapphire's Hybrid Radeon X800 GT 256MB is let down by a poor cooling solution - it overclocked reasonably well considering the poor cooler, but at anything above 485MHz core, you will be greeted with the fan spinning at full speed. Admittedly, it is not all that loud, but it is louder than any of the other cards on test here. If we disregard the cooler, Sapphire have implemented a very solid card that performs as expected at its default clock speeds - the bundle is good, there's a free game and the PCB is a funky blue/green colour.

HIS' Radeon X800 GT IceQ II iTurbo 256MB is another great Radeon-series implementation by the company from Hong Kong. There are questions as to whether the cooling solution will appeal to everyone and you can't help but think it is slightly excessive on this card. Having said that, it's quiet and if you've got the room for a two slot cooler you shouldn't look much further than this card.
