Update Intel numbers

Update Intel numbers.  Use the fastest non-extreme series desktop CPU in each family, and include which CPU is used as a note in the csv.  Rationale: the price/performance of desktop hardware is completely different vs server (or enthusiast) hardware.  GPUs listed here are (mostly) desktop GPUs, for example GTX 580/680/780.  Comparing them to server CPUs (for example Xeon E5-4657Lv2, E5-2699v3) would not be a fair comparison.  The fair comparison is fastest desktop GPU to fastest desktop CPU, which is what this update attempts to do.  An even more fair comparison is price/performance, but that would be harder - perhaps another graph :)
