Creating a second WoW folder

[Tofino]

Given everything you said the best upgrade for you imo would be a 32gb SSD and/or 2-4gb more ram. I would lean on getting more ram first . Later get a SSD. Only put wow folders on the ssd and nothing else. If you are comfortable with symlinking you can get a performance boost with that too.

I'm upgrading the whole machine in January anyway, so I'll grab 8G then. Not sure how creating symlinks helps with performance -- it's still acting on the same physical file, ne?
