Thanks in advance.
1st question, do you have 64-bit Win 7? 32-bit can only access 3.3G or so.
When the system is slow, have you checked Task Manager to see if any processes are hogging the CPU?
In order to use all your memory (in reality, you don't actually want to use all of your memory) you have to run enough programs simultaneously to require that amount of memory. Windows 7 does use a portion of your memory for SuperFetch but that memory is indicated in Task Manager as "Available".
Adding more memory to a machine doesn't magically make it run faster unless you don't have enough physical memory which causes the OS to start swapping to disk. Since you say your system never uses more than 35% of your 8G, I doubt if your memory is the issue.
