The Best:
The
ATi Radeon 9800 Pro 256MB. This card lasted me for like *3* years of GREAT PC gaming. Never had a single issue with it, and it came out right when ATi stopped sucking at driver development. It thoroughly destroyed EVERYTHING nVidia attempted to throw at it until the 6800, and even then, it still held up well. When it came out, it BRUTALIZED the competition.
Honorable mentions: the Creative Labs Annihilator version of the GeForce 2; the nVidia Riva TNT2; the 3dfx Voodoo 3 3000; the nVidia GeForce 6800 line; the nVidia GeForce 4Ti 4400/4600.
The Worst:
The
nVidia GeForce FX 5200. Yeah, it was a budget card, but it was still $200 when it launched, and it couldn't even outperform a GeForce 3 for most games, it was so crippled. The whole FX line was a joke (and huge); no surprise they were developed by 3dfx engineers who'd bailed on that defunct company to join nVidia.
Dishonorable mentions: the 3dfx Voodoo 5 5000 (lol); the NEC PowerVR line (hyped to hell by Sega fanboy idiots); the S3 S2000; the ATi X800 line (large, hot and only SM 2.0).
