Malkie,
I'm glad it helped you sort things out. With AMD iGPU systems running both CPU and GPU folding is taxing, running either by itself not so bad. With GPU only, you should hardly notice it's running.
Also, having taken a look at your returns, keep in mind that not completing work units by the timeout hurts both folding and your points. The more work units you complete on time, the higher your return percentages, and once you are above 80% finished ratio you can get bonus points if you registered a passkey. If for some reason you are not making timeout deadlines when folding 24/7 you should report it here on the forums. It's possible that the assignments are too aggressive for the classification species of the GPU if that is the case.
If you do get a discrete GPU, the CPU is more than enough. If you make the right selection you can also keep it cool and quiet, and fold a lot more points as well.
