At the beginning of October ATI launched a new series of graphic cards with Radeon X1800XT as the performance monster leading the new generation. About the same time that the cards would be released in the middle of November NVIDIA relased without warning a the least to say tuned 7800GTX card. Even if they still used the GTX name, although with the 512 addition to tell you of the larger amount of memory, you could historically call this new version an Ultra version. With just as much memory used by both cards and with NVIDIA's increased frequencies the situation has never been so even. Usually we don't talk about the overclocking until the end of our articles, but this time thought we would do the exact opposite. We usually test the cards with the stock cooler, but we thought we would change that. Therefore we hired Marcus Hultin, also known as Kinc and world record holder in all three 3DMark categories. He will with the help of dry ice and liquid nitrogen investigate what X1800XT and 7800GTX 512 can do under extreme conditions.
