64 Bit Client

[Arendel]

I read in the notes today that a 64 Bit Client is now available for WoW for us 64 bit users.
Could any one explain to me the significance of that for both single boxing and Multiboxing?

Should I get it?

Will it make any performance difference while boxing?

Will ISboxer be able to support it?
