Dont think so, performance is like 250X at low res/settings.
Currently $90-100 gets you R7 260X or GTX750
you are right, it's probably a lot slower, and with decent settings the 250X (7770) is probably also significantly better for most games, that graphic from GTA V is a bad reference for this comparison, it's CPU limited game and the VGAs are combined with a massively slower CPU
still, OC results for the IGP could be interesting, the HD 4600 had a good potential if you ignored the power usage increase
