voodoo 1 orchid righteous- awsome
I got one of those shortly after release, for some ludicrous price. Righteous 3D was what it said on the box, and it delivered. Although when I bought it, the only things that used it were a patched version of Quake and the "tower" demo that came with the card

Come to think of it, I'm not sure that the hardware 3D version of Quake was available at the time. The card was so awesome that when a friend came round and I showed him what it could do, he immediately drove off and bought one. Without asking how much it cost.
S3 ViRGE afterwards...oh dear. Wish I'd read reviews before buying it rather than afterwards. The well-justified phrase "3D decelerator" would have put me off.
I had a Voodoo2 afterwards, but that wasn't so dramatic an improvement as Voodoo was over software rendering on a 486DX-33.
TNT2 Ultra after that, which was a great card. Had that for ages, great value for money.
I had a GeForce FX5200 at one point, for a few days...oh my, that was crap. I really should have learnt the lesson about not reading reviews before buying.
Radeon 9800 Pro 128MB. Brilliant card, which I fitted with an Arctic cooling VGA silencer. It's still working today - I got it out of my box of old bits just last month because someone I knew wanted an AGP card for their father's PC. So I gave them that one.
GeForce 7800GT, which was defective. OcUK dealt with that, so I bought a Leadtek 7900GT (which had just come out). Which I'm still using today, though it's a bit past it now. Clocks to 550/850 with a Zalman on it, wound down to silence on a fan controller. Overclocked a lot, used a lot and still working perfectly. Very expensive at the time (~£250), but it's proved to be good value in the long run.
Best ever...the Orchid Righteous 3D. It would be silly now, but at the time it was mind-boggling.
Next up, I think, will be a Radeon 4870. I'm looking at a 22" 1680x1050 monitor, so I'd need something with a bit of grunt.
EDIT:
I'm going to have to sue Loque for emotional trauma. Their post has reminded me that I once owned an SiS6326 card, a dreadful waste of money that I had managed to forget
