You might have seen some colorful history shots in my posts, it's from a Boinc Manager called BoincTasks. Not only is it especially useful if you have multiple clients running (as you can remotely connect to as many as you want all on one screen), but this is a must have based on all of the other features!
 
Been using it for a couple months now and it's very stable, only time it seems to crash is when you exit it with BOINC server still running, since I don't do that very often, no real problems!
 
It can also start up the BOINC client on the local host for you without loading the default boinc manager, gives you core usage, keeps history for as long as you want, etc!
 
He also makes TThrottle which can track your cpu and gpu temps (and control them if you like) and that program also syncs with the main program BoincTasks to display all your temps in one place.
 
Here's a screen shot of mine:

 Common Bugs:
 

• There is a "no connection issue" fixed by just removing the mac addresses from the list of remote computers, so IP address only. (You can set up all clients for remote access and then do a network scan to find all of your hosts. This adds all information to the connection, just remove the mac addresses.)

No problem! Really thought I made a post about that already
