Cheapest 4 core CPU for 5-boxing?

[Lyonheart]

Correct me if i'm wrong but it seems to me an i7 is a little overkill for 5-boxing, especially if you take care of the other bottlenecks:

- SSD
- RAM
- GFX card
- dual-boxing.com bookmark

I suppose some people can't live without 60fps and high settings on all screens but from a cost/benefit point of view, i7 just doesn't make sense.

If all you do is play 5 WoWs..yea.. but i7s show big performance increases when they are OCd for apps that can use it.. like Rift and other modern games. But yea.. for JUST WoW.. the i5 K series is more than enough
