until last wow patch i was able 2 run 15 dungeon buddy on 8350 with 24gb ram (20 probebly do it ) i have my cores oc 4,2ghz i was usualy around 80-99% cpu
after lates version of hb same bot setup i can run only 10 hitting 100% cpu all the time !!!
second rig i7 4790k @ 4,4ghz (24 gb ram ) i was running 15 dungeonbuddys with cpu @ 50-60% i was using this pc 2 other stuff like some games and movies
after lates hb still 15 db but very low settings (loot radius, tps, no logs, ) its constatnt @ 100% cpu usage but botable
funny thing is that its not wow thats eats my cpu power but HB wow is usualy 2-5% per wow but HB offten hits 15% (not all of them at once,) but it eats eway all cpu power it can
