Good color gamut will make even simplest thing like your wallpaper look more vibrant, so it’s not about gaming.

For coding, programming, rendering, i think the specs (CPU and GPU) is powerful enough… maybe need more RAM if you heavily encode videos, raw images, and running virtualizations.

Color will look washed out, i personally won’t buy it.

Think about it, you’ll stare at your screen most of time.

Those 144Hz screen won’t mean a thing, you likely play most games lower than 100fps, most of the time.

But, your call.

How’s the screen color gamut sRGB/NTSC value?

This is a big deal, imho, bigger deal than 120Hz refresh rates (we rarely achieve 100 fps in games anyway, especially with budget GPU)
