Best benchmark program?

[eyetrip]

Just wondering what the best overall system benchmark is. Hopefully it is something free, but not essential, though won't spend huge amounts on something.

I know synthetic benches won't necessarily represent real-wold performance, but I want to know the effects of changes I make in BIOS, so that I can see if a tweak is making things better and not worse.

Hoping there is a suite which will test a wide variety of things, and not just CPU.

I do use IBT for stress testing, or Prime, and while I am sure IBT could give me some help, I am not sure how good it would be at showing differences in say moving from cas 10 to cas 9 on memory, or upping the bclk from 100 to 105.

I think Everest is now Aida, which I actually came across earlier, and thing that might do. It's not free, but it's not horribly expensive...
