Windows Vista & Windows XP

[KPE]

I presently have 2gb memory and would like to upgrade so it will run faster. Any suggestions ?

Your T2080 processor does not support more than 2 GB of memory.

BTW, we run Windows Vista with lots of Microsoft Office applications open at once and don't exceed 1.5 GB. Check the Performance tab on Task Manager (taskmgr.exe - press Ctrl + Shift + Esc).
