OK,

I would say do this at totaly your own risk. You are voiding all warranty and support by modding the hardware and you are at huge risk of popping your graphics card and killing it beyond repair. Once its dead no company will swap it for another, and they will know you have done it, count on it.

My opinion is do not attempt it unles you are 100% sure you are able to accept the risks. And the biggest risk is do you hae money to buy a new gForce?

Remeber this is not over clocking, this faking the GPU on the system and chips on the card, with that there is a huge risk of BANG!!!
