to see how your system meets the requirements. As far as the explode not working correctly, when you are done moving the components you might want to select the "apply" and "done" buttons. If things are not moving and reacting like I expect this is the first thing I try. You should able able to select your components drag them to where you desire and hit enter and be reset for the next explode step.
Also not sure if it applys but the subassembly button will allow you to move only some of the parts of a subassembly while having it unchecked allows you to move the whole sub with one click.
I would definitely check that the GPU is up to standards.
System requirements are good.
Selecting the "apply" and "done" buttons after each time is pretty much what I said I already tried with doing a rebuild between explode steps and it doesn't work. The parts that I am selecting are not a sub assembly so that doesn't help.
