A) The wind waker benchmark will make things look faster than they are, as it's a really light game, and the benchmark build is 3.0, which is faster than current builds, but much less accurate, so has many more bugs.

B) If you don't do anything really stupid, overclocking won't cause any damage to your system that you'll ever notice. It might drop your CPU lifetime from 20 years to 15, but there's no way a current computer will be particularly useful in 15 years. There are plenty of guides explaining how to do it safely, and it's the only way to run the most demanding games.

C) In many benchmarks, the i5's HD 4600 graphics are within 1FPS of the A10-5800K's 7660D. If you were saying the 5800K might be sufficient, then it's likely the i5's will be too, and you'll also be able to get dolphin working well. Either of these integrated GPUs will be just about enough for games, as they're similar to midrange graphics cards, and should be able to tide you over if you try and save up some money to get something better later. That's probably the best option for your budget.
