TweakTown posted a review on the XFX GeForce 7900GS Extreme

The 7900GS which we have with us today sits at the top of the mid-range or the bottom of the high-end range, which ever way you want to look at it. Designed to compete with the X1900GT in price and performance, it should be an interesting battle. While the 7900GT from nVidia is normally consistently ahead of the Radeon X1900GT, it is also more expensive so both cards offer excellent value but if you’re on a strict budget, you will most likely going to choose the cheaper X1900GT. The new 7900GS is placing nVidia in that low $220 USD ($300 AUD) bracket again.
