The inertial and gravitational mass have to be the same for conservation of energy. Consider the thought experiment where you have two metal spheres isolated in space apart from one another each with zero velocity. Their gravitational mass accelerates them together for a collision (let's say perfectly elastic), they rebound in the opposite direction and their inertial mass keeps them going against the gravitational pull between them until they are apart again with zero velocity by the same distance , at which point the whole process repeats.

That's the chip I have too, and upgrading to an SSD was a huge leap. Another thing was upgrading the graphics card from a radeon 3850 to a 6850, now it runs all the new games like Bioshock Infinite on high settings. If I upgrade anytime in the near future it will probably be because the new chipsets can pay for themselves on power savings, I haven't done those calculations yet.

The way I explained why gravitational mass and inertial mass are the same is by considering the thought experiment of two balls in space starting off a ways apart, they gravitationally attract and then kinetically bounce apart, if inertial mass and gravitational mass were different they would either eventually become stuck together or drift infinitely apart which can't happen due to conservation of energy...
