JavaJones said - "PSU's without enough power, heat issues, questionable RAM quality, overclocking, unnecessary resident programs, etc."

All true but, how does SP2 "fix" those issues?
It doesn't...as you said..it only highlights them.
The best fix would be to address "those" issues directly.
Which would negate the need for SP2 at all...no?

Also...Zak...Dual channel IS better/faster. If your RAM is hot..cool it...simple really!

Be aware though..that not all ram is equal.
Dodgey RAM IS the biigest issue in 99% of cases.

It's a shame stupidity isn't painful.
