If you're defining 4K@60Hz or 4K@120Hz as the left extreme of "decent quality", then sure.

Legacy Blu-Ray discs maxed out at 1080p30. Most people would consider those discs to be "decent quality" (or more realistically even "high quality") video, and a $400 video card is well capable of playing modern games at (or even above) that resolution and framerate. The entry-level 5060 cards are also good enough for video games released at this time, in either memory trim.
