By limiting dolphin possibilities do you mean reducing aa, internal resolution, other other in the graphic page. If that the case your running into a gpu limit not cpu. You might also get more performance by overclocking the cpu if you haven't done that. Also compile shader before start will help with stuttering.
I don't know if the ASUS ROG STRIX 470X-F is a combo deal but it might be worth looking into a x570 chipset as it will still support the r5 2600(check the cpu list to be sure for the motherboard by mine does), cost similar from what I can tell, and have pci gen 4 support with a ryzen 3000(non g) or 5000 cpu which may be useful in the life of the computer. If you plan on a ryzen 9 in the future it would be wise to look at review for vrm quality though as some board vrm's get really hot with cpu fully use for a long periods. B550 don't support any cpu before 3000 series(non g) so you know and aren't confuse just in case.
If worth mention since the cpu are cheaper from what I can tell, that intel i3 or i5 like the i3 10100 or i5 10400f can be found under 200 dollars and will be faster then the r5 2600 in dolphin. The downside is the upgrade path is worse since the r9(especially 5000 series) cpu are better in general then the i9 cpu. The intel 10 gen also don't support pci e gen 4 either and the 11 gen while supporting pci e 4 are limited to 8 cores for the high end.
As for the 1080ti assuming hybrid ubershaders you might be fine at 3x ir and 8x aa but high will like struggle. The mention setting is the equivalent of 24 x of the original resolution and that is questionable even for that gpu in every game. This would be true if you use the i5 2500k or a modern cpu.
