It would seem that the Geforce fx on paper is about where a Geforce 4600 ultra would have been.I was looking for the Geforce fx to really be a brand new part,but it seems like the same tech.I know we have no benchs as of yet but if the fx is any faster than the 9700 pro I'll be very surprised. I think nvidia is in trouble with this new part,they totally under estimated ATI,even an under clocked fx that costs less will have a hard time competing. I hope I'm wrong about the fx and it really does bring something new and better to the table.
Geforce fx = Geforce 4600 ultra?

Don't know what you think this post of yours will accomplish, buddy.
The GFFX has about as much in common with the old GF4 as the Radeon 9700 has with the Radeon 8700, ie, not much at all.
There has never been a "GF4 4600 Ultra" announced, nor even rumored.
And considering Nvidia's said the GFFX will be faster than the 9700 it would be mighty strange if it was not. I certainly expect it to be, though by how much is open to debate of course.

Pixel pipeline wise you can certianly see the architectural evolution. The vertex Shader end appears to be all new though.
Well technically speaking, while there are quite a few huge differences, changes, additions, and so on, technically speaking GeForce4 is just a highly evolved TNT.
TNT + Clockspeed = TNT2
TNT2 + TNT2 + HW TCL = GeForce256
GeForce256 + Additional TCU's = GeForce2
GeForce2 + Pixel / Vertex Shaders = GeForce3
GeForce3 + ...um... LMA2? = GeForce4.
Of course it's more detailed than that but you can technically reduce it to that. I guess what way is speculating is that
GeForce FX = GeForce4 + DX9 Pixel Shaders + Additional pixel pipe per TCU - DX8 Vertex Shaders + Massive Vertex FP array.
It IS a pretty big jump though. I doubt it's still an evolution of GF4... but we'll see once the S3TC results are in
Keep your eyes on the Q3A sky!

Considering the age of the specific game, the rendering power of recent accelerators and amount of on board ram, give me one good reason why someone would opt for texture compression in q3a?
Finally not even the GF4's Hardware DXT1 decompressor uses the old 16bit colour interpolation of it's predecessors.

I've complained about that aspect myself, especially the aniso algorithm. Albeit mostly based on software modifications, from the user side 6xS and 8xS are an improvement over current 4xS and 4xOGMS methods.
My biggest grief with the NV30's AA pipeline is the lack of 4xRGMS, unless it's present and I've gotten something wrong here.

Doom 3 is more DX8 class hardware than DX 9...Doom 3 doesn't use displacement mapping, or Vertex Shader 2.0 or PS 2.0...
The only real gain a Dx 9 class card will get you may be overall speed due to the improved hardware (faster memory modules, 256 bit bus).
Doom 3 doesn't require a DX 9 card..it requires a 256-bit bus, 800 mhz DX8 class Radeon 8500/Geforce 4.
