overkill and bottlenecks.
why sabertooth? you can get the job done very well with a cheaper board.
560ti? seriously?i would recommend at least a 7950 or 670 if possible.
why 10k rpm? samsung f4 2tb for $120 is the sweatiest spot for hard drive.
crucial>intel for ssds.
750w is enough for 670 SLi and overclocking.
BTW,what's your max budget and what you are going to use this rig for?
