Its in the thermal properties of the material.  Read this chart of thermal conductivities.

 OK I just installed a 680 and did a quick run of vantage with a 3820 @ 4.625 Ghtz.  This is what I got. 100MGz OC on 680. But what seems different is something that I'm wondering if maybe it's just my imagination. But I swear vantage ran smother than any other I have ever run. Meaning So fluid regardless of FPS.
 

i think my block might be too small.
 
my internal design only leaves me with 1/6 of an inch for the first inch of the block.  i honestly dont think its enough.
 
will have to work on it some more.
 
 
also nate, your Gcode what format is it saved in? the program im useing might be able to export in Gcode. i can export in Directx lmao

This is my old Vantage score when I had Tri GTX 580 1.5GB

ehh, there is a bit more to it.  When you say export the g-code you will need info from me like, max safe z, end mill diameter, Depth of cut, climb/conventional milling and some other stuff.  Some pics of what your working on would be nice. 
 
Oh and tru_gamer... that radiator setup is wild!  Looks like its as big as a car radiator for a small car!
