What it costs to run
190W 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 →
Why you buy it
- 12GB VRAM at $249 MSRP
- Legitimate 1440p entry performance
- Drivers improved dramatically since launch
Why you hesitate
- Needs resizable BAR to perform properly
- Street price often floats above MSRP
- Occasional driver quirks in older games
The editor's take
The best budget value on paper: 12GB and 1440p-capable performance at a price NVIDIA will not match. The caveats are real but shrinking: drivers keep improving, though older titles can still surprise you, and it wants resizable BAR enabled to perform. Stock and street price wobble; at $249 it is a steal, at $320 the math changes.
