I'm not trying to sound like jerk (seriously), but REALLY man your CPU is FAR from bottlenecking those ancient cards.... your bottleneck is more the other way around....
You should really consider upgrading to a single 7970 in Jan and ANNIHILATE those 4k cards.
Also You will see MINIMAL to no difference in FPS with an overclock on that 2500k with those cards. Mind you that you have one of the most potent CPU's for gaming as of right now and will have no problem smoking through anything paired up with the right cards.
Here's mine I ran the free basic version to see how it stacks up to the ones posted, notice the high numbers. Using specs in sig rig.
