Tom,
You are most unlikely to be able to notice the difference with or without
PAT. There are so many other factors that influence performance that to
notice a difference you would have to look for it using benchmarking
software.
Ditto for an upgrade to the higher spec processors. a 3.0 to 3.2 GHz upgrade
is 1/15th (6.67%?) = sod all. Improvements above 25% can be noticeable in
some situations. If you want a performance improvement to be worth while
think about it when you see 2x to 3x or more. IE wait for 6GHz and get value
out of your current system.
