Not really, in newer and more graphically advanced games the 6800 series are slower than the X8X0 series, you can see it in the Tom's Hardware VGA Charts, in games like F.E.A.R, Oblivion etc. So is useless having 3.0 and HDR without the horsepower to run it, anyways there's nothing different in image quality between 2.0b and 3.0, you can see it in games like Age of Empires, Far Cry etc. Anyways, an equivalent to the X800 PRO in AGP should be the 6800GS, the X850 PRO is faster and should compete with the 6800GT. The 6800 Ultra competes with the X800XT and blah blah blah.
Hmm wrong.
AOE3 is a VERY good example of the difference.
Since you mentioned THG,
S.M 3.0 cards can activate better IQ in tomb raider legend
Difference of PS 3.0 and PS 2.0
The 6/7 aseries and X1000 series enjoy HDR, parallax mapping etc plus the THG has a final comparison between the older cards to the new ones.
The 6 series have a MUCH better IQ now due to many games taking advantage of S.M 3.0. Firstly, when S.M 3.0 was introduced, it was used to optimise GPUs for performance rather than IQ. Although a card like a 6800GT could be slow to take advantage of S.M 3.0 IQ enhancements, it will still be enough to play future games at a lower res (maybe without AA or even AF), e.g 10x7 with all those features enabled unlike the X8 series which will miss all those out all together.
edit - Some will say its too slow to play with all S.M 3.0 eye candy, but this is subjective as some people are FPS sensitive, or doesnt mind playing at lower res without AA or even AF. (Well the 6 series been out for quite a long time, so you would have to expect the level of pofermance to be quite low).
Not to mention future games might not even provide a S.M 2.0 backup shader, and instead be S.M 3.0 only. They might have a backup shader model at 1.1 which shows considerable IQ loss as seen here.
HardOCP's S.M 3.0 article.
Naturally, Future OpenGL games will perform great with NV hardware (even the 6 series), unlike the X8xx series which get slaughtered in OpenGL titles. (X1000 series does pretty well which is a nice thing).
Maybe some users with 6800GT/6800GS can post some benchmarks on todays games.
