Verdict
At $259.99, the RX 580 costs about 10% less than the $289.99 Arc B570. That $30.00 saving is real money, but not so wide that the pricier card is out of reach.
Budget-conscious buyers have an extra option: the RX 580 can be found used on eBay around $79.00, roughly $180.99 below its new street price. If you're comfortable buying used, that saving could shift the value equation between these two cards.
