[GPU-Z Test Build] Fix for NVIDIA cards with 4 GB+

http://gpuz.techpowerup.com/12/07/29/50h.png

Works for me, let me know if you need any info for completing support on the 680M

GTX 670 4gb

First, thank you all for a great utility, a great forum and a great resource here on techPowerUp.

The memory reporting fix works fine. My question is, are there other things it's not reading. The sensors tab only shows like half the amount of fields that my 480 shows. Is that a change with 6xx series of cards or is it something that still needs to be implemented in GPUz?

Cheers
