cool bits or rivatuner?

alright fellow gamers which app should use to tweak my nvidia card.
I havent had much interest in this area before i run stock 90% of the time (OC the FSB a bit) so help is would be nice.
pros and cons both would be good as well.

I use RIvatuner; it supports almost all the stuff on your card (even the number of pipe lines and stuff)

This program is very good, you can tweak the texture format or other hidden features like texture filter distance and other. .
I love it

One problem that I found is the saving future , yes it does saves , but if you want to save several settings , although you have the option its not really working , so therefore its always One setting that you have and if you want other you'll have to change it all the time ..But overall its good :thumbup:

I don't know the other program sorry .
