you have written 'h.264' - this could be AVCHD, could be .ts, could be 120fps, could be .r3d, could be anything!
I am unsure if my project is set to this
you're using a highly professional software - you should know at last, what you have choosen on 'New Project'.

not using 'optimised' plus using non-standard 'video' (=I assume) could be the cause for your problems. FCPX is meant for camcorders as source. It allows. although, to use it for 'any' sort of video/files. but, on final export, that stuff has to undergo heavy processing = time.
being myself no good psychic (my crystal ball's broken lately), hard to tell from remote WHAT are you trying to acccomplish … if you don't know.
'pimping' the hardware will not solve this riddle. if you would tell us, what exactly is your source (format, codec, res, fps, audio, 'source' like camera, sat-recorder, 'internet', converter/which one) , plus your settings in FCPX (project, export) we probably can improve performance.
