Everyone wants to play gaming at a 1080p resolution with 30 or 60 frames per second. However, all the mainstream cards are enough to play at these settings and provide greater performance with realistic graphics. Whereas, if you would prefer 4K resolution with your gaming experience, then select the high-end graphics card with 1080p 4k resolution with 60fps would be the best choice.

  •  Keeping in mind the refresh rate

Refresh rate mainly depends on your monitor, if it is providing somewhere triple-digit the fresh rate then you will need to select a powerful card with full performance.

Before buying a graphics card always make sure that you case enough room for a graphic card as buying a large graphic card with a cooling fan and having a small room may result in a wastage of money. Additionally, always check the power supply, whether it delivers the power as required or not.
