It's probably just me being out of touch, but I don't think the GeForce RTX 4000 or 5000 series really mattered/matters that much. At the same time I'd add the S3 ViRGE and the Matrox G200. Both mattered a lot at the time, but not long term.
> S3 ViRGE and the Matrox G200 Both were only really famous for how terrible they were though. I think the S3 Virge might even qualify as 3D decelerator ;)
Last time I saw a Matrox chip it was on a server, and somehow they had cut it down even more than the one I had used over a decade earlier. As I recall it couldn't handle a framebuffer larger than 800x600, which was sometimes a problem when people wanted to install and configure Windows Server.
