The card is fine with that system. In fact, you can go with a faster card if you want. The PSU has the +12V rail specs to handle more. And the aging Phenom II has enough oomph to keep up with a RX-470 or GTX 1060 3GB. Both ~$200 US.
But the RX-460 will do nicely as well at 1080p.
Thank you for your assistance, I will stick with that card, trying to stay on a budget, if he wants better, he'll have to get a job.
30 rebate is what is making the sale
