BonaFideReviews posted a review on the HIS X800GT Turbo 256MB graphic card.

A couple days after our fair well to AGP with the HIS X700 review we get back to the lovely PCI Express bus. What better way to do it then with a review of the HIS X800GT Turbo. This card features the R423 ASIC, 8 pixel pipes, 6 vertex engines, and 256MB of GDDR3 memory. The reason why the card is the "Turbo" version is because it comes with HIS's iTurbo overclocking software which overclocks the X800GT's core and memory frequencies with a single click.
