After looking at two KT400 boards from the first-tier manufacturers, it wouldn't do justice if we had left Gigabyte out of the picture. Gigabyte has always been one of the more popular brand among users, whether power users or just the general consumer. Gigabyte boards are almost always laden with some of the best features and it's no surprise that their next flagship DDR400 board for the Socket-A platform would come with the same on-board devices.

Manufactured in a blue PCB, it's hard not to admire the beauty of the board with its golden heatsink and colour-coded connectors. Ease of setup and idiot-proofing seems to be the top priority for Gigabyte and their formula is proven as it has been well received by users. Even little details like rounded PCB corners were made an important design consideration as Gigabyte's engineers believe in giving users the total product satisfaction - from the minute the user open the package until it's fully operational.

For those who do not know yet, the VIA KT400 chipset is VIA's latest offering for the Socket-A platform. Supporting AMD's Duron and Athlon XP processors, the chipset also has the ability to power up the latest AMD Athlon XP processors at 333MHz FSB. In addition, gamers with the latest RADEON 9700 PRO and GeForce4 Ti 4200-8x would be able to take advantage of the larger AGP 8x bandwidth.
