Guessing its going to be hardware related and I would like to know how to get this thing running seamless.
Your computer is quite similar to mine. The potential issue I see is the video being on USB hard drives - if they are USB 2.0, that is not a good option, USB 2.0 is too slow for video editing. USB 3.0 with fast drive would be fine (I use a G-RAID 4TB external over USB 3.0). For now, try moving the video to the internal SATA drive and see how it plays. Another issue is that you are not benefiting from the GPU acceleration of Mercury Playback, no Nvidia graphics. Makes a BIG difference!

PPro before the cloud does not support crossfire... and that may cause problems

USB2 hard drive is too slow for video editing
External eSata or USB3 are both fast enough for video editing... eSata is better - http://forums.adobe.com/thread/1117813
ONE possibility is this $47 USB3 dock with fan http://www.amazon.com/StarTech-SuperSpeed-Docking-Station-Cooling/dp/B0055PL2YI
