The PX7900GT Extreme have some subtle differences that is not apparent until you look at it a little closer. The heatsink is shaped in such a way, that there's only one exhaust present - the right side of the cooler. The fan is slightly further to the right, making the cooler slightly longer than standard coolers. In short, this means extra heat dissipation area which is a good thing. Now, look closely at the fan, you'll no doubt notice Leadtek chose to use a lot more blade than usual. Using such a design can have some drawbacks - mainly noise - so it was a pleasant surprise to find this card is barely audible in operation.
The packaging is your typical Leadtek packaging, something which we have much praise in the past. Inside the box, you'll find the standard accessories: a HDTV dongle, a DVI to analog dongle and a 6 pin ATX power cable. It would've been nice to have at least two DVI to analog dongles, but apparently that's optional depending on where you live. The game bundle is the same as with PX7600GT Extreme - Serious Sam II and Trackmania Nations. Of course, the obligatory installer CD with utilities and DVD playback software are included..
A peek at the fan control tab in RivaTuner confirm our suspicion - to keep noise down, the PX7900GT Extreme uses slightly lower values on the fan control slider.
However, this compromise shouldn't affect the thermal performance of this card since its heatsink's dissipation area is larger than the other cards. Let's see how the PX7900GT fares after a session of Quake 4.
A full load temperature of 62° Celsius is average, typical of what we saw with a GeForce 7900GT. Unfortunately, we didn't have the time and equipment to do any noise levels test, but from our experience the card is no better or worse than any other GeForce 7900GT. In this regard, the PX7900GT Extreme is not that different from any other GeForce 7900GT. It will have to rely on its performance and bundle to differentiate itself from the others.
