Sorry I'm not a gamer so I have no idea about APB, most of us Idle in the low 40's, Running Furmark will stress your GPU I think low 80's with 15 minute run, I don't think I've seem my CPU at over 72 after 15 minutes full load. There are lots of Furmark test threads you can search for to get a better idea Games will never push your GPU or CPU as hard as Furmark or Burn In test You can get a pretty good idea how good the pasting is by running these. A good Benchmarking program will test your complete system. 3DMark is another program that a lot of people use to test there graphic performance.
