The rage3d tweak was rather annoying to me.
Took me awhile to figure out how to disable those noises it makes.
The Radeonator, and Powerstrip, work also too.
The Powerstrip makes you wait 5 to 20 seconds on your bootup thou. (unless you buy a license)
I dont use any.
My OEM card didnt allow much of an overclock. so, I dont use them.
Cuz I'm overclocking my CPU.
Overclocking the card just adds another variable to wonder about if I'm having oc problems.
