Tool Suggestions?

I just want to ask for a good tool that i can use to check my CPU and Video card temperature? and also what tool i can use to see the usage percentage of my Video card? i tried Process Explorer but it doesn't work on Windows XP.

MSI Afterburner has worked in giving me CPU & GPU temps as well as GPU usage, and you can have it as an overlay in full-screen 3D applications if you want to watch how specific games work your system and don't have a second monitor.

I will try that, Thanks!
