Looks good, the G2010 is an entry-level CPU and the Radeon 6670 is an entry-level card, seems like a nice fit. I don't see any bottleneck, the 6670 isn't that powerful from the start, so you would need an older CPU to bottleneck it.
For the 6670, try to get a DDR5 version if you can. It makes a big difference in performance compared to DDR3 models. You could even get a 7750 if your budget allows it.
