Quadro FX 2500M driver

I have a Dell Precision M90 with the following specs:

Intel Core 2 T7400 (2.16 GHz)
4 GB ram
250 BG SATA HD
Nvidia Quadro FX 2500M video card
Vista 64 Buisness
Solidworks 2008 (sp 3.1) 64 bit
3dconnexion navigator
microsoft wireless mouse


The performance has been terrible, I suspect the issues are relatedto video drivers. I have tried several that I have found on severalsites with some level of improvement. So, my question to you ishave you found a driver that works well for you? I typically workwith large assemblies (10,000 + parts). I am almost ready to scrapthe 64 bit and go back to XP 32, shame though to go backwards. Ireally like the Vista 64 look and feel.


Thank you in advance for you help.
