Either a 1050ti or an RX 560. The 1050ti is the better of the two cards, but is also generally a little bit more expensive. Here's an RX 560 that's within $5 of your target price.
Pss dont listen to people flaming you cause they are good enough to recommend 1080 but poor enough to buy you one. In 125, i suggest ebay , get an old r9 280x or gtx 960 and you will be golden
