I had some trouble with mini-freezes, particularly when mouse driving (little hitch and suddenly you're facing 30-180 degrees from what you were). For Bards trying to swarm kite, this is a deal-breaker. 
 
I'd look at your HDD. EQ seems to depend heavily on fast read times to run smoothly. Either run from a SSD or try loading your EQ folder into RAM if you have an abundance (8G or so). 
 
Maybe not the same thing you're experiencing...
