VSPTree and Nehalem's

VSPTree uses the Visual Studio 2008 Team System Profiler for profiling and will cause bluescreens due to a bug in windows. There is a hotfix, unfortunately the installer will only install it if you have VSTS installed! Not that standalone... which is what VSPTree uses. :(

Alternatives are :

AMD CodeAnalyst

Very Sleepy

Both are simple enough to use, but CodeAnalyst has the advantage of having a VS Plugin... however, that VS plugin crashes VS when it tries to show the results....So they're equal in my mind.

CodeAnalyst does have the ability to filter the results better, both are simple enough to use.
