Please help me

What System should i use for Maya and a Geforce 2 GTS
I´m using Windows XP now with Detonators 30.82
The Performance is umm ok sometimes the Hypershade
Thumbnails are just VANISHED (???)

What do you think about a Windows 2k System with SoftQuadro drivers 26.xx or tuning with RivaTuner to a Quadro and install
the Detonator 30.82 as Quadro Driver ?
