Tech-Hounds continues their look at the X1900 series from ATI in the second part of their indepth examination.  Find out more about  the differences between ATI and nVIDIA than just the PCB colour. 
“ATI’s latest offering, the Radeon X1900 XTX is strong, but it does have its weak points. We already covered the lack of performance with texture dependent games in our last article. Now we discovered that ATI’s adaptive antialiasing is not as effective as NVIDIA’s transparency anti aliasing. You don’t really gain that much image quality improvement, even with Quality setting.

However, we also saw that ATI is putting the Radeon X1900 XTX as a forward looking part. HDR performance is way stronger than the GeForce 7800GTX, even in texture dependent games like Serious Sam II. In shader heavy games like Splinter Cell Chaos Theory, the Radeon X1900 XTX is simply on a higher level than the GeForce 7800GTX. Of course, the icing on the cake is the ability to use AA with HDR, something the GeForce 7800GTX lacks.”
