Overview

GeForce 6800 XT is an NVIDIA GPU entry in the GeForce 6 Series family. It is listed with Curie architecture and NV41 silicon.

Key reference data: 256 MB GDDR3 memory, 256-bit memory bus.

Board-partner cards can vary in cooler, PCB, display outputs, clocks, BIOS behavior, and power connector layout.

Why It Mattered

GeForce 6800 XT belongs to the Curie and GeForce 6 Series era around 2005, when PC graphics cards varied heavily by bus, memory chips, BIOS, cooler, and display outputs. Tracking the exact model helps retro builders distinguish period-correct boards from similarly named variants.

Collector Notes

For archival use, record the board vendor, PCB revision, bus type, memory chips and capacity, BIOS version, cooler or fan, display outputs, TV-out or DVI adapter cables, and photos of both sides of the card.

Used-Market Caution

Before buying used, confirm PCI or AGP voltage compatibility, required legacy driver and OS support, visible capacitor damage, fan noise, memory artifacts, missing breakout cables, and whether the card has been tested in period-correct hardware.

Known Issues

Known issues pending source review.
