What it costs to run
263W of board power, 4 hours a day under load, priced at the residential electricity rate where you live. Pick a state and the numbers update.
Board power is the rated maximum; real gaming load usually sits below it and idle is a few watts, so treat this as the ceiling. Rates: EIA residential average, May 2026. See every card ranked by running cost →

The editor's take
The 9070 replaced it, but retailers keep clearing stock and the used market is full of them. At the right discount this is still one of the smartest 1440p buys around: 16GB, proven drivers, known quantity. Pay attention to the price gap to the 9070; when it narrows, buy the newer card.
