Sadly, they really do not for gaming. APUs are recommended at the absolute lowest end of the spectrum but it is much better to get a discrete gpu in almost all cases.

The i3 outperforms the 6300 by quite a bit for not much more, which makes the 6300 quite limited in value too but it is used in certain builds at the bottom end such as http://choosemypc.net/build/?budget=420&oc=false

The 8350 really lacks in single threaded performance for gaming purposes

AMD CPUs have not been refreshed in a while and are now sadly showing their age vs Intel competition
