Editor freeze when i drag a mesh

I have a TITAN GTX, 16 gigs of ram, SSD Drive and a Skull Trail Dual CPU Motherboard with Core2 Extreme X9775s at 3.20GHz (2 of theses 8 cores…) Same issues. These are not “Game Ready Assets” so keep that in mind when trying to use them in a project. Would love to know if there is an asset pack out there, I am teaching a class and this version of UDK does not come with nearly the amount of stock assets as older versions. Any help pointing me in the right direction would be appreciated. Thanks in advance.
