6600GT. Slighty faster in games, better feature set/drivers.
6600GT is slightly faster, features= no.
Ati can do dynamic brancing and geometry instancing, better than nvidia apparently.
But if things don't change, the 6600GT is a tad faster, but I think there's some nice gains to had with catalisy A.I, not to say nv wont do the same, however.

No they can't dynamic branching, it is not just for lights, and thats all ATi can do, its not true dynamic branching since ATi can do 512 instructions per pixel shader they just did a combanition shader of 3 lights in one pass, Sm 3.0 complient hardware can do 4 lights and more if special measures are taken.
GI is capable by ATi but can be done by any card sm 1.0 and up if programmers to find this one out but it can be done. In Ogl it is much easier to use with Vertex Bound Objects.
Hmm..rancor said:
it will be 2005 before SM3 is the norm me thinks..
Atleast untill both have SM3 cards, kind of like 3DC, its not an ati only feature, nv can use it, but its just kinda there, not really needed, but Hl2 will use it, as you know.

I find this highly amusing. Please continue.

Its general accepted by whom? does futuremark come out and say there is shader replacement goin on, does Epic say this, does, Blizzard say this, does Id say this, I want to see the words from the people that working with nV say this. and backed up with proof of differences with screenshots and shader analysis, Take doom 3's shaders and run them through a shader analyser, and show me this.

PS: are these all "TWIWMTBP" (whatever) games ?
ati did that in 3dmark 03 way back, no one complained about the iq, just that they were replaceing shaders.rancor said:
They do it doom3"In Doom 3, there's actually a bit of shader replacement going on. For example, the game uses texture lookups to determine the values of specular lighting fall-off rates, essentially reading a precomputed value by fetching that value from a texture. It just so happens that ATI's hardware can compute the algorithm faster than it can fetch the answer from a texture, so that's what it does: It replaces texture lookups with the math it approximates. The result should be identical, but with a significant speedup."
Looks better in some parts.
Moloch said:
They don't look the same specular highlights have changed, and that goes back to there is no way to do shader replacments without some changes. Without the shader replacment it has hard pressed to tell the difference between the two cards, (of course aa and af you could tell) but with it, just look for brighter gloss effects.
