I have recently upgraded one of my home computers and now I have an extra set of 1066 DDR3 sticks (8GB combined). My office computer is a Dell Vostro 260 with a Core i3-2120 and 4GB of 1333 DDR3 memory. Is it a worth the time to install the larger capacity/slower speed memory in the system? Currently the system is used for Office apps, PDF creation, email, and the occasional lunchtime Minecraft distraction. I do keep multiple windows/programs open at the same time (Right now I have Chrome, Word, Excel, Outlook, AIM, Acrobat Standard, and my Contract Software all open.) Thanks for the help.
