Doom 3 is Nvidia's baby

According to privleged press that have had their hands on Doom 3 it seems to us that ATI is doom3d. We saw the first numbers which clearly show that the NV40 marchitecture rocks in Doom 3.
Source: The inquirerBoth Geforce 6800 Ultra and 6800 GT are significantly faster then Radeon X800XT Platinum or X800PRO.
Our USA friends at HardOCP showed us that at 16x12 High quality and 4X FSAA and 8X Anisotropic filtering 6800 Ultra gets almost two times faster then X800PRO and in all but one benchmark Nvidia dominates.
In 10x7 high quality no FSAA and AF ATI can keep up with Nvidia cards but that is the only time they can be as good as Nvidia or marginally slower.
This does not come as a surprise as NV30 can render 8x0 in Doom 3 if your rendering pass doesnโt require Z-buffer or Color information and in many case Doom 3 doesn't need them or extraordinary 32x0 in Doom 3 with NV40 marchitecture.

Get this:
1600x1200, maximum detail, 2x aa, 4x af, the game is capped at 60fps, and I'm averaging 60.5fps.
6800GT @ 350/500 (1000), 2.59GHz 2600m, 1GB PC3500
Remember that the beta 4.9 is called "Doom 3 Hotfix" or "The Doom 3 Driver".
But I think that it is bad that Doom 3 had to come out, before Ati would optimize the OpenGL performance.
The ATI crowd remind me of the 3D-FX fan boys from the mid 90s - desperately trying to tell everyone how 2 x Voodoo2 cards ran faster than the Geforce, despite the fact that the Geforce was the better card.
My understanding is that the current hierarchy is this:
X800XT > 6800 Ultra > 6800GT > X800 Pro > 6800
The X800XT should be faster than the 6800 Ultra; they're both 256-bit, 16-pipeline cards, and the X800XT has faster RAM and a higher GPU clock.
And although I'm an ATi person, I ended up going with the 6800GT this time... nVidia finally "fixed" their image quality so it's basically on par with ATi's, and the 6800GT is faster, I believe. I would've gone with the 6800GT even if it were a little bit slower though... I'm extremely unhappy with what ATi did with the X800 Pro, as I was with what they did with the 9600s. I don't appreciate them crippling my cards for me.
