Yeah I would think so too. Sadly it hasn't for anything that is flash based. HTML5 works perfectly, Quicktime works perfectly, unless I just got done using Flash and the quick time file is HD.
That's disappointing 🙁 As a last resort, you might consider using the OS restore discs that came with the laptop? (Whether it's 10.4 or 10.5... just another thing to try)
I'm still unclear on this. How do I know how many threads I have? What am I looking for?
Since you have a two-core processor in your MBP, open up two Terminal windows and run the command in both of those windows. That will act as a stress-test on the laptop.
