What would be the best settings for running GameCube\Wii games on my PC?
I can't seem to find the right combination of settings.
Here's my specs:
OS: Windows 10 x64.
CPU: Intel Celeron G1610 2.6 GHz Dual‑Core.
MB: MSI H61M-P31 (G3).
GPU: Gigabyte Radeon R7 240.
Well, for starters I have to say that you probably aren't going to run anything too demanding at more than 1xIR with that computer. I don't know which settings you have already tried and what has worked so far (maybe you could clarify that a little bit?) but as I said the first thing I would do is to set the resolution to the lowest possible setting and go up from that.
Depending on the game there can also be different settings that give a free speedup, so I'd play around with those. Here is Dolphin's official compatibility list (including the game-specific settings), if you haven't tried it already:

IR won't be an issue. They have a dedicated GPU. They can turn that up without any problems. Doesn't matter if it's low end. A low end AMD or nvidia GPU still outperforms an Intel GPU by leaps and bounds in Dolphin.
Their problem will by their CPU. It's not great.
