I am on the verge of buying a used AGP geforce 6800 GT or Ultra depends of what is available. The purpose: to softmod into a Quadro FX 4000. Now, I have read lots of the RivaTuner posts regarding the mod, that only the NV40/45/48 can be modded 100% and the newer 6800 nu/ngt cards are using a different chips like nv41 or other. So everything I have read so far kind of bends my mind and Id like to purchase a card knowing for sure it will be softquadroed without problems, but, Im not 100% sure: any 6800GT or 6800Ultra are softquadro moddable? Are there any exceptions? Which ones? Any brand that is 100% moddable? Stay away from which cards? Should I ask the vendor to install Rivatuner and send the Report to be 100% sure? Thanks. Konstantin.
