Hmm lets see,
Trident 512k on my 386
added the socketed other 512 for a full meg on my 486
Geforce 2 in the pentium (good old PII celeron A, overclocked 50% from 300 to 450)
the P3 600 was a laptop with an Ati Card, no end of trouble, every driver update was a 3 hour ordeal. Every EQ patch required a new driver, which had me offline for nearly a day to get it working.
P4 was an Ati 9200 at first, not bad, but soon upgraded to a 9800 SE, see above.
Departed with the agp to a pcie x800xl, another set of driver nightmares.
7900 Gt, first card I really liked
Got a great deal on an x1900xtx, so gave ati another shot, spent $200 on parts trying to get it working, reinstalled os, gave up, turfed the card on ebay and put the 7900 back in.
8800 GT 1Gig, my new fav card.
-edit- bottom line is I cant deal with Ati's crap drivers, will never go back
