Performance in First-Person 3D Shooters
The PowerColor X1900 XT is a little slower than the Radeon X1900 XTX and the GeForce 7900 GTX in low resolutions. Overclocking helps to close the gap, but not to beat ATI’s flagship product. It’s different in 1600x1200 where the graphics memory bandwidth is vitally important: the GeForce 7900 GTX can’t keep up the tempo and finds itself about 10% behind the non-overclocked PowerColor.
The Chronicles of Riddick
The non-overclocked PowerColor X1900 XT is somewhat better than the GeForce 7900 GT. Overclocking helps it compete with the more expensive Radeon X1900 XTX, but the GeForce 7900 GTX remains unrivalled in this OpenGL-using application. Anyway, the PowerColor X1900 XT delivers a comfortable frame rate in two resolutions at its default frequencies, and in 1600x1200 too at overclocking.
