ATI FireGL solutions perform best in Maya and AutoCAD, while Nvidia takes over the leadership in SolidWorks and 3ds max.
Look at the tests again, it depends on if you use the SPECapc or SPEC Viewperf results for those two applications, they flip-flop for both apps (SPECapc favours nV SPEC Viewperf favours ATi).
The realworld performance is very close especially in those two.
As for the models, for both nV and ATi is makes sense to try softmoding if you want to save money, but even the gaming cards will handle it fine.
The softmod on the old GF8800s is a little easier though IMO.
The instructions on how to softmod to FireGL are actually at Guru3D, the main issue is getting the device IDs to match an existing FireGL card, and then doing a little cut and paste work. Result seems a bit more stable in Maya from my experience, but not sure about 3DSMax which can be finicky even on dedicated workstations IMO. Check out the Quadro softmod mention of the 3DSMax versions it has trouble with.
IMO, the most attractive option would be softmoding an HD4670 GDDR5 into a FirePro V5700, but first you have to have ATi release the GDDR5 HD4670s to the consumer/gaming market.
