Please note that the XFX GeForce® 8800 Ultra XXX is essentially a factory overclocked version of the original NVIDIA 8800 Ultra GPU/VPU which is at best a variant of the original 8800GTX VPU/GPU. There have been no apparent major changes to physical body of the card or features (other than sheer speed) since the release of the original 8800GTX. For that reason we will somewhat abbreviate our normally in depth "Features & Specifications" section of this review and place our efforts where they belong with the card itself and in its testing.



Power Consumption

We decided to measure both the power consumption of our entire test system with each of these cards. To measure power we used the software that came with our UPS that measures line draw. We used a high-end UPS as our power source to eliminate any power spikes and to condition the current being supplied to the test systems. We measured the idle load after 15 minutes of totally idle activity on the desktop with no processes running that mandated additional power demand. Load was measured after running 3DMark06 for 15 minutes at maximum settings.

As we would expect, the power consumption of both these graphics solutions is high and we can certainly understand why a power supply with minimum of 35A on the 12 volt rail is recommended. The best answer is get used to it and buy the absolute best PSU you can afford if you want the luxury of running either of these products.
Temperatures

The temperatures of the cards tested were measured with Everest Ultimate Edition v. 3.50.761 to assure consistency and remove any bias that might be interjected with the respective card's utilities. The temperature measurements used the same process for measuring "idle" and "load" capabilities as did the power consumption measurements.

While not totally out of the realm of what we expected to see, the temperatures are higher than we'd like. However, they are somewhat lower than we expected and totally within an acceptable operating range. We were quite impressed with how cool the XFX 8800 Ultra XXX ran throughout the testing staying within 2 degrees of its counterpart. It truly makes us wonder if the cooling used by XFX is truly the standard NVIDIA reference cooler or an XFX variant. Remember also we were running these tests in a closed Lian Li PCV-2000 custom built enclosure in a room that is kept at 20° Celsius (+ 1°. The moral is these high-end systems produce quite a bit of heat in a direct relationship to their power consumption. So make sure your case has plenty of airflow.
