You can make an argument for either side, with the SM3.0 stance. For ATi it obviously was not cost productive to add it, and their core was mainly just an update. So they just waited a year or so till more games supported it, and more are in development. It can be said that there are hardly any games that support it, and the ones that do, take a huge hit when graphically enhanced over 2.0.
NV on the other hand added it, and have helped games to advance faster in that aspect. Pushing forward is hardly ever a bad thing. It can also be said, that games can look better with 3.0, over 2.0, and giving the user the option (sometimes) to choose between the two gives them more control.
To me, both can be "right". I would rather have companies pushing forward though, as NV did. I would think it was easier for NV to add it, than ATi. ATi is not "copying" NV by adding 3.0 in their next card. Obviously they would add it without NV anyways. They both took different approaches, and any one of you may have very well made the same choice being behind the wheel of the company.
The truth is though that 3.0 doesn't make an image quality difference. And even if the X800 core is just a small update, it still outperfroms the 6800.
ho ho ho
both cores are good, Nvidia had to radically change the way they think because there was no way they could of derived NV40 from NV3x, simply no way. NV40 was a completely new approach.
r420 was a doubling up, and optimization of the tried and tested R300 architecture...nothing wrong in that, but its not gonna have the life span
SM3 doesnt make too much of an image quality difference no, infact probably zero, less u count farcrys HDR, all SM3 does is make it supposedly "faster" to perform the same operations as SM2 can, and add a few things SM2 cant do. the only way IQ can benefit is when SM3 makes it possible to execute a shader at a fast enough speed to be playable, where SM2 would of been to slow to execute the same thing.
nvidia definately has ATi on features, Ati definately has Nvidia when it comes to AA and AF, and in my experiences of having both ATi and Nvidia cards i can say that IQ is just the same.
Nvidia had to pull something out the bag, to make up for the NV3x disaster, which they have, they released a beast of a card, which is the most feature rich too, if they gonna start from scratch they may aswell get in all the newest tech they can, that way they can gain more understanding of it, and in future revisions make it better
Ati on the other hand had a great design (from artx?) with the R300, they had the best products all the way up to 9800XT, there was no need for them to put alot of time an effort into a new design incorporating all the new features..it wouldnt of made sense. for them it was definately better to just take what they had, tune it up and make it faster. that way they can deliver all the performance needed, with minimal cost in the R n D, it was a wise choice to leave SM3 out for R420, its not really needed by any games out now.
nvidia were starting from a blank sheet, so while they were at it, they might as well cram it full of features, simple as that
