Matrox Mystique (dont remember specifics)
3dfx Voodoo 3 16mb
GF 2 GT 32mb (pretty sure thats what it was, 2000 seems so long ago.
GF4 TI 4200 (at this point I have a better memory)
GF 6800GT 256 agp
ATI Radeon HD2600 (last ditch effort to upgrade aging p4 platform) after reformatting and 2 different cards, a new PSU, I couldnt get the a driver that worked right, wierd texture issues, like the mapping was off, on every game) ultimately returned
GF 7800gs sad thing is I never really got any use out of it, this PC ended up going to my gf as I said screw it and built a new PC, after rocking my frankenstein PC that was just upgraded and hodgepodged from pc's that were given to me over an 8 year period. As of january 2008, one of the HDD's in it was from 1998 (recently died the other day as my girlfriend wondered why her pc was clicking and freezing, that thing lasted 11 years, what a hard drive)
GF 8800GT 512 (G92)
GF 9800GTX + 512 (freebie to me, included it in the cost of a system I built for my mom gave her my 8800gt kept the 9800gtx+ not that she would ever even utilize the 8800gt)
I intend to try ATI again in the future, perhaps with my latest planned build, but that experience still sits in my mind. Never once did I have an issue like that with an nvidia card.
