It just rubbed me the wrong way, so I decided to stop giving my energy to it.
This is a useful test, 2C, in so far as the stated goals goes. It's not necessarily going to provide a 'universal' answer, that applies to every situation, but in terms of assessing the general ? of whether there are games that seem to be able to take advantage of >2 cores (and if so, at what number of cores do the performance improvements 'max out', and does HT work the same as addt'l cores, or no?) ... it's a sound methodology. Esp. since he's using both Intel and AMD for the tests.
Also important is to test with relatively low gfx settings so you won't 'miss the effect' by making yourself GPU bottlenecked instead. I would also look for areas in the game to test where you tend to see <99% GPU usage (if you can find any) as this generally indicates a CPU constraint (but not always).
Keep in mind also that testing at different CPU clocks (and comparing % change in FPS vs % change in clocks) as well can be useful, because those tests can more positively confirm whether you're being CPU-limited in the particular testing scenario you're running. If +10% cpu clock = + 10% FPS, you know your are 100% CPU limited where you're testing at in the game.
I second the Crysis 3 request ...

Miserably threaded, and hopelessly CPU bound. Just look at this:
45FPS (with all four cores enabled) despite my ensuring that the GPU was out of the equation.
Actually, those reflect a fairly nice improvements from the additional cores. You're unlikely to see significantly better results in terms of % improvements in many of these tests. Going from 76 to 108 is a 42% increase in FPS, going from 2 cores to 4 cores .. I bet if you do this same calculation for all the games, you'll discover that's fairly good 'return' overall. You shouldn't expect to see 100% in this case. That MIGHT happen sometimes going from 1 core to 2 cores, but not from 2 to 4. Games are not like video encoding software.
