Stucked up on Eurocom GPU stock driver :( Help

Helo everyone,

firstly I am proud to be member of such a community. Many of people I know(from Czech Republic) are getting registred and use this forum as the most reliable source of advices, information and trobleshooting on the internet.(my opinon). I have been reading here about 5 months. Registred just last week.

Now my question.

I purchased EUROCOM M860TU. Couple days ago I reported here some issues.
Today, I found out that:
My rig works on its full performance only with Eurocom stock drivers 176.02

When I install drivers from nVIdia (179.28) my rig peformance is like I am running it on battery only ( which Im not, I am on cable) and getting about 3-40003DMarks 2006.

The same problem with dox 180.43 drivers.

I just cant force this machine to perform about 9K in 3Dmark on any driver except my old stock one. I feel very poor, because these are kinda outdated. I have lower perfomance in 3D mark and even in games(new drivers are released due to fixing bugz and enhancing performance right?)

Every 3DMARK run on non-stock drivers is like battery perfomance, I tried to disconnect adapter, changing profiles in Vista and cant get it out of it.

I think nobody here uses stock drivers on such laptop.

Have anyone experienced something similar?

Thank you for reading this and any suggestion are very appreciated.
