Thanks for the excellent reply.

I will order 4GB more RAM or possible just buy a fresh lot of 8GB where everything matches.

Can anyone give me any advice on SSD vs a normal SATAII hard drive? I want a second disk where i symlink (that powershell script someone linked was fantastic for making clone folders). Essentially I would have two copies of wow one for my 'main' one for 'clone1' and symlink the other 3 folders of clone1 so that my mods can be different.

I know benchmark wise yes there is probably an advantage to SSD but in practice and espeically with mboxing is there any noticable difference?
