Bjorn3D posted a review on the PowerColor X1900 GT Video Card

The introduction of RADEON X1900 series brought bannana type smiles to our faces. ATI customers were happy to get more raw power for their SM 2.0 / SM 3.0 games. Beginning of 2006 ATI however offered only high-end boards and no cut down versions were available. Until Q2 2006 if you were in the market for new Canadian processor you were either stuck with X1900 XT or XTX -- great cards, but expensive and bulky. Around May, ATI decided to kick NVIDIA's green buttocks and take on GeForce 7900 GT. With that in mind, RADEON X1900 GT has been introduced.
