When NVIDIA launched the 7800 GTX graphics card back in June 22nd it was by far the fastest GPU on the market and ATI had nothing to counter it with. ATI finally did launch a counter in the form of the X1800 XT on October 5th and was able to return to the neck and neck race that we had expected. But ATI's card was using 512 MB of memory and a very high frequency while the NVIDIA 7800 GTX GPUs were only using 256 MB and still quite a bit of headroom in them for overclocking as many of our reviews have shown.
