Well, another weird list... I didn't comment on 25 yrs of Ati, becasue it was too late when I first read the article.
I agree with people who think that the title is really wrong.
1) Either way, you should've included real tops (like X850XT PE instead of X800XT, the 'true' and the last red king X1950XTX with the limited Uber edition signed by Ati CEO himself) as well as some other cards...
2)Why bother with interim GF2 GTS if nV dished Gf2 Ultra half a year after the first of the 'second generation VPU' as they called it, as well as the dying man's vain attempt to regain leadership with GF4 Ti 4800.
Anyways, as I see it, the 'greatest cards' were not the top-priced ones, but those 'overclocker-oriented' ones:
1) 8500 LE - great card with a great chance to unblock the HyperZ and other missing features with one registry tweak (sic!) contended with lower priced GF3 cards and was better at colour/2D because of superior RAMDAC
2) a 'transforming' duo: 256-bit/4pp 9500 (non Pro, many people here apparently don't know Pro version was 128 bit / 8pp and that s**ked) -> 9700 + OC and 9800 SE -> 9800XT. People literally hunted for Sapphire SE cards with 128 mb DDR1 packed in BGA
3) on Ati's side:
a)X800 Pro with Rage chip -> X800 XT PE - hardmod unlock, not so great but it was a good tradition to unlock ati cards those times
b) Gecube and Sapphire X800GTO2 256 mb DDR3 - a fully functional X850PE at X800 non-pro price... It was like you got $250 for $400 card. People hunted for those too.. Savvy dealers here in Russia sold those at a *MUCH* higher price because of that. Personally I had an 'ordinary' X800 non-pro with infamous R430 chip, which didn't overclock and all unlocking attempts failed (probably pp were laser cut)
on NV side:
a) A zillion of GF 6800 'value' cards - all those 6800 LEs, 6800s had a good chance to be unlocked into full 6800GT and overclocked to ultra if you had VF700 CU. Author of this article forgot (accidentally or not) that PCIE revision of the NV40 was not unlockable, hence those cards were not as attractive as X800GTO.
b) Certain 6200 cards did unlock into 6600 ones, but i remember not that many.
c) 6600 was the undisputed king of mid-range gpus, so it was a VC of choice for many gamers who didnt bother with AA or AF.
The next generation:
a) NV continued to hold the throne of mass performance market with their 7600GT cards - ati got their competitor - 1650Pro only a year after the 7600.
b) X1950 Pro was the choice of the time, good price for great performance.
Further generations:
I remember certain 9600GSO 384/768 Mb boards were in fact, G80 or G92 cards, which was cool. It was 8 times faster than my contemporary notebook M56 (aka Radeon X1600) GPU.
