With the 3dfx/STB and Diamond/S3 mergers, two of NVIDIA's biggest supporters are now out of the picture. Looking at it from the other perspective, that of a board manufacturer, the only big graphics manufacturer left that is offering up chips to board manufacturers is NVIDIA. This of course provides for a perfect setup for every graphics board OEM to jump into the fray and offer a variety of cards based on NVIDIA's latest chip, current the RIVA TNT2.

Gigabyte is one such company that is a fairly well known on the motherboard side of things and has quietly played the video card market in the past. As a motherboard manufacturer, they've proven their abilities in the AnandTech labs with rock solid motherboards that seemingly do no wrong. Although they've been in the graphics market for quite a while, the GA-660 TNT2 is AnandTech's first glimpse at a Gigabyte video card.
