ati catalyst control center is probably the easiest overclocking program (although it isn't overclocking specific) out there, at least in my experience. all you have to do is slide the bar and click ok. the testing on it sucks though. it says "pass" on settings well past a passing grade. for checking the overclock i like to use ATITool. it has a great artifact detector that colors the artifacts in yellow so they are easy to see. there are others also, of course. you just have to look around and find some that you like. also, i haven't come across any brand-specific overclocking tools like xfx or asus. has anyone used one that works well?
