Now, the only thing WoW is missing in reference to effects is tessellation (but i don't believe WoW will ever bring that in).
Indeed. Not to mention, the review doesn't even state where the measurements were taken. In fact, it doesn't even give us an indication of what sort of benchmark was performed. Was it while standing in an empty area, and if so, what area? Was it done with timetest and if so, what flight path was used? There's many question that aren't answered.
As said above, MoP added Ambient Occlusion. This is a pretty heavy effect for GPU's, and will reduce frames by 20-30%.
The extra 4 logical cores make little to no difference for WoW -- not because "it only uses 2 cores" as is regularly spouted (which has been disproven many times but simply because the number of 'high-processing' logic threads is still relatively limited), and the clock speed, being only 100Mhz higher, will add around 2-3% framerate (though, as you can imagine, add 3% for every 100Mhz quickly adds up, so a 4.7Ghz overclock as used there could add up to 36% FPS increase).
Of interest, you can see from the review just how much difference resolution makes. The average FPS reduction is 22% at each resolution increase, and interestingly, the 1920x1200 to 2560x1600 is the biggest jump (29.57%), even though 5760x1080 is 3-screen gaming (2560x1600 to 5760x1080 is a 25% reduction). That can be explained by the 78% resolution increase between 1920x1200 to 2560x1600, vs the 52% between 2560x1600 and 5760x1080.
