On a side note, wasn't the card not bad for DX8? it just tanked in DX9 if memory serves me right.. It had some questionable IQ regarding AA but AF was good.. so long ago!
No, it was bad in DX8 too because to get decent IQ, you had to use the highest quality settings and performance bombed against ATI quality mode, that still managed superior IQ at the same time. Most reviewers tested in Balanced mode as a result, which is why 5000 series looked good in benchmarks but was junk in the real world, except OpenGL and flight sims where ATI had serious disadvantages at times. What made it worse that when it came out late, it cost $100 more than a 9700Pro and with stock cooler it was unusable which meant spending $50 more for an after-market cooler. As a result you ended up with a ~ $450 FX5800U against a $300 9700 Pro. Back then gamers were much less brand loyal to NV so it was inconceivable for an unbiased gamer to pay $100-150 more for NV that had worse IQ.
You could also bios flash the 9500pro into a 9700, and once ATI brought out 9800 Pro and 9800 XT, it was all over for the 5800/5900 series. Ironically the biggest NV fans still bought 5000 series at the same. I am not going to name any members on our forums but those who owned 5000 series and skipped 9700/9800 have exclusively owned NV since then too. Ownership of 5800/5900 series is pretty much a gauranteed barometer of "pointing out NV fanboys." The lower end cards such as FX5200-5600 were even worse. Thankfully 6800GT/U series was excellent.
