Confused on nVidia driver

I have G92 8800gts 512mb and still using the earliest G92 nVidia driver 169.06 released on November last year.

While on the official nvidia page said the newest 175.16 driver:

Supports GeForce 6, 7, 8, and 9 series GPUs

Some peoples said nvidia will release more 169.xx driver specifically for 8800 series.

Which is the best drivers so far and is 175.16 works with for G92 8800gts card?

well it is a beta driver, but its working great on my 7800gs
and i don't see why it wouldn't work for a more modern card.

I was rcently similarily confused - until I found out that I use a beta-driver I once downloaded too.
