Hyperthreading and Multiboxing

[yurano]

As the title suggests, would a HT CPU like the i7-2600k be better for multiboxing than the i5-2500k?

Assume that we are running at least 2 instances of WoW simultaneously. The master instance of WoW must have high performance. The other slave instances of WoW must still run, but do not need to be as responsive (graphically) as the master.

No significant difference.
