I brought a Imation ssd drive home (pro7500) and used it for a symlink ./Wow/Data on the machine I am trying to work on consolidating 5boxing machines to. Definate speed increase loading, zoning, flying I would say. That's about it and all I would expect, this machine also has a Killer M1.

Likely overkill, but with the money people seem to dump on graphics cards not so much. I would choose the Killer first.
