So my question for you guys is:
1) How good is 4 GB of RAM for WoW in your opinions.
2) If you know any way I can successfully install this RAM. (By the way, the back of my computer has a small icon with a 10 and arrows going around it in opposite directions in a circle, and the RAM chip has the same symbol, but instead of a 10, it has a 20.
Please help and answer these !
