For us performance nuts owning nVidia cards, another great utility, NiBiToR, has been updated. For those who haven't tried it yet, like Coolbits and nvclock it is software designed specifically to help you tweak your GeForce card. Unlike the others though it isn't software or post-boot tweaking – it lets you change card BIOS settings, which influence things including memory timings, voltage used during different power states and – very neatly – the speed of the GPU fan. If you are into tweaking and have a GeForce, grab it. Be careful though!
