get live windows , but not stats overlay?

[rockit50007]

i multitable 7-9 tables at full tilt and only getting the stats overlays on only 3 or 4 tables at most at a time, while still getting all the stats live windows. i have been reading the stats off the live windows but it is inefficient and time consuming, also because i have to stack the live windows on top of each other to fit on my screen.
I have a 20,000 hand database and am currently using a pentium 4 , 1.8 Ghz ,1 GB RAM;
Would getting a faster computer help me get the stats overlay to show on all 9 tables?
Any other suggestions to improving the performance of poker office?
Any help would be appreciated as i am making bad calls , folds, raises AND tilting as a result of not having stats quickly to hand.
