I have no idea what I'm going to do when we get to the 8xxx Radeons. First serious card I got after my ATI Voodoo5 64 was an ATI Radeon 8500 128. There should be some sort of rule about model numbers looping around.
Yeah, well they did add the HD in front, so technically it's a Radeon HD
My first Radeon was a 9800 Pro, top card at the time, but my first serious 3d card was a Rendition Verite V2100 from Diamond (1997) which would run accelerated vquake and that I overclocked massively from 40 to 60MHz by adding a heatsink on the chip. I'm not counting various iterations of "S3 Virge" before that, which never really ran 3d games. Fun times...
