It's 2 times as fast as your Core 2 Quad since Dolphin is a dual core application
Depending on the generation , i5 and i7 may be strong , may be weak . 1st gen Core i7 (Nehalem) is much slower than 4nd gen Pentium / Core i3 (Haswell)
You may want to look at Dolphin Benchmark
But I wouldn't recommend a locked multiplier CPU like Pentium G3220 . Unlocked Pentium G3258 (Anniversary Edition) is incredibly cheap and can be Oced @ 4.6GHz with Intel stock fan
