It doesn't seem all that long ago we were saying that while Doom 3 was certainly able to give a system a run for it's money, it could also be quite forgiving on your hardware with the right settings, thanks mainly in part to the dark nature of the visuals. Today, the HIS X1800GTO has hardly been fazed at all by Doom 3, giving us some very solid frame rates at a high resolution and with high image enhancments. 4x Anti-Aliasing, 8x Anisotropic Filtering and a widescreen resolution of 1680x1050 provide an excellent game experience with this card. As expected the X1800XL does provide less drops in the framerate than the other two cards here, but the X1800GTO's numbers are close enough that you would be hard pushed to tell the difference while playing until things got very hectic on the screen.

Quake4 has had quite a troubled childhood, but the latest patch (1.2 at timing of writing) does a lot to clear up the majority of problems and certainly improves things as far as using it for video card testing. Our HIS X1800GTO IceQ 3 Turbo puts in a very strong showing here against the two comparison cards; an X1800XL and a 7600GT. Remember that the HIS card is overclocked out of the box and this allows it to keep ahead of the 7600GT and right on the tail of the X1800XL. Looking past the numbers, the gameplay experience is pretty similiar across all 3 cards, with the X1800XL only making a difference in the most intensive situations.
