The screen is only acceptable if you will be doing excel or text mono colour. If you are going to view movies you will need at least 100% sRGB and preferably P3 for official releases.
I would be ok with the screen for non-gaming purposes. I appreciate the high resolution and respectable sRGB coverage, though I would prefer a 16:10 aspect ratio and a tad higher contrast.
The response time isn't ideal to begin with, and is certainly out of the question for any fast-paced gaming.
Then there's the room for improvement in the refresh rate, which can only be fully realized once the response time issue is addressed.
The C315 Blitz swaps out the older 11th gen Core i7 H-series processor for a newer 13th gen Core i7 P-series option. However, the change is more like a sideways step than a leap forward in terms of performance.
