I'd go with the asus rig that tea urchin posted above and i'd have to agree with him about not going with prebuilt rigs especially from company like that. most of them just go big with a certain part of the build and cheap out on all other components. also if you were to build yourself the rig from scrap trust me you will get a lot more for your money and when anything goes bad you'll know how to fix it or atleast find out whats wrong its also a very fun hands on activity and just great feeling all around.
