Lots of good ideas, especially funny ones ( like a webcam deathmatch ).
Really, don't know what I should do first

Linpack, folding, etc as long as it's @ Real-time priority, and 100% load they're applying approx. the same load, I selected F@H to do two things at once ( help the community, and have fun with the Vtt myth ), so I'll stay put with F@H for the time being.
If a CPU is going to die due to high Vtt it will die at some point running Prime, or F@H, or a game, etc.
