What does an increase to 8 TeV get you?

So the Large Hadron Collider is being upgraded to run at 8TeV for 2012, up from 7TeV in 2011. The total energy of the colliding protons is bumped up by a bit, so how does that change the energy of individual quark collisions? Matt answers such interesting questions.

One curious factoid of note: out of 100,000,000,000,000 proton collisions in the current data set, exactly two of these collisions had constituents (quarks, antiquarks) which collided at more than 3500GeV. These are the unlikely events that you need a LHC to find, things that happen twice in one hundred trillion events! ]
