Time for PCI-E (at last), but which one? - Page 2

post #11 of 37
on a 6800gs i dont think much since it really doesnt have the muscle to run high resolutions with the eye candy turned up which is where the 512mbmemory comes into play.

What sort of difference does SM3 make over 2 (or is it 2.1?), and what sort of difference is it? Does it improve performance or enhance visual effects and by how much?

Well it smooths out the picture some and its needed for HDR, but not many games use SM3 yet and itll probably take a while.

Not much, but it can't hurt. The Geinward GLH series are supposed to be amazing.

SM3 and HDR makes translucent objects and bright sunlight/reflections much, much more realistic. Also, if you care about benchmark scores at all, the X850XT will suck in 3DMark 06 because of its lack of SM3. I say get the 6800GS, it's a great card.

SM3 is like night and day compared to SM2... and when running HDR, its needed and wow does it look awesome, the only performance gain you see is when a program/game need the SM3 capabilities to run it, if you only have SM2 it wound work nearly as well and lok even half as good, so your best bet is the 6800gs

It's that 'needed for HDR' that I was worried about. One of the main reasons for this upgrade is to prepare for The Elder Scrolls Oblivion, one of the first games to ship with HDR lighting, hmmmmm.
While I was looking around it seems odd that this article said:"Fast HDR rendering in DirectX can be done using GPUs which support Shader Model 2.0 or higher."
http://en.wikipedia.org/wiki/High_dy...X_Shader_Model

Is this just lying or old news or what?

there was a thread around where i saw non SM3 cards running HDR i doubt it was to its full potential. If your that worried about it get the GS.
