She has a $1000 budget but she would prefer it to be cheaper she also needs a mouse and keyboard and a monitor. The PC only is needed to run game and be able to play she doesn't plan on streaming or any video capturing. Please and Thank You!
Something with an i5 8400 or R5 2600 or better and a GTX 1060 6gb or RX580 and 8-16GB will play anything at 1080P pretty well. See if you can fit that into the budget.
