Something in Dolphin is stressing your CPU beyond what it can handle in the dev builds. Its possible something in the DC-Netplay branch isn't as intensive.
Don't open the Graphics tab during a game, it can break something in the game and cause a crash.
When was the last time you re-applied thermal paste? The CPU could be under too big of a load during Dolphin, and it throttles down in a way that Dolphin doesn't like. Dolphin could be trying to pull resources that are being used by other programs, which is why you get a speed boost when there's barely anything else running.
Comparing PC games to Dolphin is not a good way to show off your computer. Dolphin relies on single-core speeds on the CPU to work, where PC games rely a lot more on the GPU. Dolphin also tends to be more CPU intensive than PCSX2 (PPSSPP is lightweight). In PCSX2, you can get away with old Intel and AMD APUs/FX CPUs and get near-to-full speed, while in Dolphin you basically need an Intel Core i- series CPU to get near or at fullspeed, due to the way Dolphin is and has been optimized.
