Introduction

The G92 is currently NVIDIA's hottest (not temperature) GPU. It sells like mad on several different products like 8800 GT and 8800 GTS 512 MB. Since both of them are still fairly expensive and ATI has solid offerings in the $170 range, NVIDIA decided to create the GeForce 8800 GS based on the G92 GPU but with less performance features. They took G92 cores and disabled 24 shader units and 4 ROPs. The memory bus has also been reduced from 256 bit to 192 bit which explains the odd memory size of 384 MB.

EVGA being an early adopter has secured a large allocation of the 8800 GS and is one of the first companies to offer their products on the market. The card follows the NVIDIA specifications to the letter, other companies offer preoverclocked cards here for a small premium. However, as we will see later in the overclocking section there is no reason to spend any extra money on the factory overclocked cards.
