1080p vs 1440p

[tezza192]

I have a question regarding the difference between 1080p and 1440p in terms of system resources.

 

Is resolution purely down to the GPU or does the CPU come into it?

 

IE does it put more strain on CPU playing at higher res or does it purely come down to the GPU core and VRAM?

GPU since the CPU does more AI calculations and other non-graphics calculations.

The GPU core and VRAM will defiantly take a hit.

 

As aforementioned, the CPU does some physics and AI calculations that don't scale with more pixels, but I'm unsure on how the amount of draw-calls changes with resolution (Intuitively you'd think it wouldn't change, but if there are more objects on the screen as a result of having more screen real-estate you'd see a hit (more telling the GPU what to render, resulting in more computation).

What's important from a resource point of view is to understand the requirements of a game from the CPU first... Then the GPU. You just need that CPU grunt for stability of frame rate... Then GPU grunt will let you flex your resolution muscle to 1440p and higher. You can't overcompensate 1 for the other. Of course some games are CPU bound(GPU doesn't matter like StarCraft / wow / LoL). However GPU bound games (like crysis 3) are far more demanding overall so the CPU is just as important as GPU.

I'd go for a 1080p monitor, less strain on your GPU but still very high quality monitor, 4K monitors are just ridiculous.
