Hello!

Cheers or the replies, rigged something up last night and gave it a whirl. Have a spare machine with an Athlon 64 3700 single core with 2gb of RAM, this was able to run three instances of WoW with fairly minimal slow down. I then purchased two copies of keyclone, put one on the main pc and the other copy on the spare pc and gave 4 accounts a try (Warrior and three Mages) and it all worked perfectly! With that in mind I've decided to downgrade the slave pc to a dual core athlon rather than a quad core2duo. I could run all five from the main pc however I'd prefer to keep it to running just a single instance of WoW purely because it's runs a lot of other cpu heavy apps in the background. The dual core setup will be dirt cheap as I have most of the parts anyway just need a board, processor and another copy of keyclone(comes to about £70ish)

Looking at the team setup again going to give a Hunter, 2x Shaman, Priest and a Prot Warrior a go.
