Hello,
I was wondering, for Game Playing, ie. World of Warcraft. Which is the best to buy if I want to upgrade to 4GB and how can I tell what speed my OS is? I have Windows Vista Acer Model M1100.

Contact Acer to buy matching memory for that model.

While it's perfectly possible to mix and match memory, it's safer to just buy a matching set if you are new to fiddling with it.

There are lots of ways to see what speed your memory is currently running at. I personally download and run CPU-Z and read the memory tab.
