Is there an app i can use to limit the CPU usage of other programs?

like an advanced task manager? because the "set priority" thing is doing nothing to help me control this one program that often decides to take 50% or 100% CPU

Well, I use Process Tamer by DonationCoder, which effectively limits the CPU usage by programs but not on an individual basis, if that's what you are looking for. You can give it a try to see if it meets your needs, it's also freeware. You can sign up to the forums for a permanent license key or if you choose not to sign up, you can get 60 day license key which is obviously renewable.

Process priority only changes the priority of execution each application gets, if you have a few heafty apps running and you set them to low priority, that means 'normal' or 'higher' priority processes will get preferential process scheduling. It will not, however, stop the low priority apps filling in CPU time when everything else is idle. Nor should it.

If it's a multithreaded app you can assign it to a single CPU core and limit CPU utilisation to that core alone. Beyond that, kernels have no mechanism for limiting CPU core usage, because there's no reason to do so.
