PSA: 3DFX Voodoo Cards bringing high prices!

In searching the Bay looking at used NVidia card prices I saw where 3DFX cards from the late 90's/2000 era were bringing high prices. Vintage gaming rigs seem to be a thing at present. I had a pair of non working(and listed as such) Voodoo 2 cards that went for $365 and a PCI Voodoo 5 that sold for $300. They paid for my new 1070 and then some. I thought I'd post and let folks know who may have some of these lying around like I did. I thought they were pretty much worthless. This seemed to be the place to post. Some of the older Geforce and ATI PCI and AGP cards are bringing a few bucks as well. But not what the 3DFX are. S!
