ExtremeTech takes a look at the video quality of DirectX 10 hardware:
Another factor is the increasing prevalence of widescreen, high-resolution displays. The 20 or 22-inch, 1680x1050 pixel display is getting to be mainstream, while power users are flocking to 1920x1200 pixel displays, such as the Gateway FPD2485W or the Dell UltraSharp 2707W . If you have a larger widescreen display, you'll want the best video quality possible, especially when watching HD content.
Today, we compare three different GPUs, two from Nvidia and one from ATI. The two Nvidia GPUs are the 8600 GTS and the 8800 GTS 640MB. We're also testing ATI's latest HD 2900XT.
We realize that we're just scratching the surface on what is becoming an increasingly complex process at this point. We'll update our results with newer ATI HD 2400 and 2600 GPUs in a few weeks, but meanwhile we'll discuss some of their features in this article. We'll also be adding more test discs to the mix over time..
