Same binary.  Not the benchmark, building frames for my animation.

I don't care about any of that.  All I care is that POV-Ray finishes
twice as fast. :)

Yes, I typically see around 20% increase in throughput with my i7 vs. an
i5.  It *can* float to near 100% on occasion, depending on what I'm
looking at.  One thing I always thought odd, my kitchen volcano scene,
where I'm looking at the floor (superellipsoid tiles with a box for
grout) the i7 is actually 5-10% slower than an i5.

I've noticed a Ghz decrease in my last couple of boxes.  From 3.4Ghz to
3.0Ghz and now 2.8Ghz.  Certainly that will run "cooler".
The box is in the living room and is silent, as opposed to my i7 which
has dual fans that have a teeth-floating harmonic.
