Hi, I have a couple of questions about choosing a processor.

I've been five multi-boxing off and on since BC mostly just quests and dungeons. I've never really had a great system but it hasn't really bothered me much for what I do.

I'm putting together a computer of spare parts to handle a couple of simple things in the office. I figured I would take the opportunity to upgrade my CPU/Motherboard from my main computer/boxing computer. I've been looking at Intel Core i7-5820K Haswell-E 6-Core

I was wondering if that's a decent $350 or $400 CPU for boxing or should I be looking at something else in that price range. Probably looking to stay exactly around the $400 on the CPU. I see the i7-6800k at 3.4ghz for $50 more ($439)... Is that the difference? .1 ghz. I guess my major problem is I'm having trouble differentiating the processors past the basic core and ghz stat.

I hope this isn't too broad of a question......
