Dolphin is a dual core application . Hyperthreading is useless for it , multi cores CPUs (more than 4 cores) are useless too

i7 4970X is Ivy Bridge E , not Haswell . Base on Dolphin Benchmark , Ivy Bridge E is 5~10% faster than Sandy Bridge but Ivy Bridge use TIM paste instead of fluxless solder between the CPU die and the Integrated Heat Spreader (IHS) -> As a result , Ivy Bridge overclocking capacity is worse than Sandy Bridge
So I would say no improvement at all
i5 4670k / i7 4770k is recommended here . Pair i5 4670k + MSI Z87 G45
Do not buy non-k Intel CPUs and non-Z87 mobo , they can't be overclocked
However , Haswell uses TIM too . You better wait till Summer , you could buy a new unlocked Intel CPU (code name : Devil Canyon) which is superior to older Haswell in term of overclocking
