Before I read this article, here is what I consider Greatest cards, based on priceperformance... Some of them, I owned.
(order of age)
0 - Amiga (Because back then... PC was pretty much 16 colors, if that)
1 - 3DFX Banshee $99 / 1999 (Not quite as fast or expandable as the Voodoo2, but cheaper with 2D support)
2 - GF2-MX $125~150 / 2000 (128bit version), cheaper than the GF2 GTS & Ultra, get 24bit pallet for cheap.
3 - GF2-Pro $150~175 / 2000 (OEM card originally - far cheaper than the Ultra while almost as fast)
4 - GF3-Ti200 / 2001 (Half the price of the original GF3, DX8 is new)
5 - GF4-Ti4200 $200 / 2003 (blows GF3 out of water)
6 - ATI 9500/9600 / 2003 (First serious ATI cards)
7 - GF-5700/5900 (Fixed the screw ups from the rest of the GF5"FX" line)
8 - GF-7600 = At $185~200, it smoked any 6000 series card for the cheap.
9 - GF-8800GT = Hitting the market at $250, not quite as fast as the $650 8800GTX - but far cheaper.
(This GPU gets re-named, repackaged about 5-8 times from Nvidia, even ends up as a 200 series card)
10 - ATI 3850/70 = $175~200, ATI returns to the market with a good-enough card without the heat. Starts price war with Nvidia.
11 - ATI 4670 = $90~100. Equal to the 3870 but half the price. (Still what I use today)
After that... my list pretty much ends. The ATI 5700 series is decent at -$100 pricing. At this point, we're past the classic pricingperformance.
