Hardcoreware posted a review on the Gigabyte NX76T256D-RH Silent GeForce 7600 GT. Here's a bit:

Comparing the $150 GeForce 7600 GT to the Radeon X1650 XT might have been a tough battle from the get-go. After all, the X1650 XT has an average price of around $250 or more. But that's what I have, and in the end it makes the 7600 GT look even more impressive for keeping up in most tests, and beating it in others.

Gigabyte gets bonus points for making this a completely silent solution, although the cooler is quite bulky. For those who don't require absolute silence, Gigabyte makes one with a standard temperature-controlled fan as well.

In the end, if you're looking to spend absolutely no more than $150 on a new video card, the GV-NX76T256D-RH is a good one to turn to. It runs cool, quiet, and can play the newest games under moderate levels of quality. What more can you ask for from a $150 video card?
