I knew from this forum about ability of gf 6600 core, NV43 rev. A1 and A2 mod to Quadro. And earlier revision can not modded. Mine is rev A2. 1) Anybody has mooded it to Quadro? Maybe a short tutorial, please. And please your testimoni about it stability. I use CAD and 3dMax. 2) Is it a same / equivalent to 6800 mod at http://forums.guru3d.com/showthread.php?p=1636176#post1636176 ? 3) Mine, Leadtek Winfast 6600T, 64 bit bus, not 128 bit, if it real quadro has 128bit bus, is there any problems with the mod? 4) What "quadro" will i get from 6600? Thank you. Sorry for my poor english.
