Mine were set to 3 and I changed it to 15. I have since installed 5 wow folders symlinking them all. It seems to help alittle however the two accounts that are on the same core affinity get bad fps. My accounts on their own core affinity get from 10-15fps in dalaran. The 2 that are on the same core get 3-5fps.

I am specing a new system and plan to raid 0 2 of these http://www.newegg.com/Product/Produc...82E16822136319

I will then use one of these as my storage/backup drive. http://www.newegg.com/Product/Produc...82E16822148337
