3Dfx Banshee AGP
A prototype 3Dfx Banshee, though it's close to a production Banshee like the Innovision Mighty3D. Today companies copy the reference design but back in 1998 it was less common. In other words: you can find Banshee's in all kind of shapes even though the design of 3Dfx works fine .
This sample didn't come with a heatsink but for sure one is needed to run the card. Never apply power to a Banshee without a heatsink installed as it will overheat fairly quick.
