Is this monitor good for photo editing?

Yes. The 27-inch IPS panel's high pixel density and stable colors suit photo and video work. Check that your GPU can drive 5K at 60 Hz over your chosen cable.

Can I connect a MacBook with one cable?

USB-C carries video and can power a laptop, so a single cable setup is possible. Confirm your model supports 5K output over USB-C or Thunderbolt.

Is it good for gaming?

It is fine for casual and strategy games, but the 60 Hz refresh rate is below what competitive shooter players expect. The dual-mode feature helps in some titles but does not match high-refresh gaming panels.

Does it have built-in speakers?

The listed specs do not mention speakers, so plan on external speakers or headphones. Check the box contents for the cables included.

How does it compare with a 4K 27-inch monitor?

5K gives noticeably sharper text and finer detail than 4K at the same size. The trade-off is that 5K needs a stronger GPU and more bandwidth, so older laptops may be limited to lower refresh or scaled resolution.
