This is why I have a 3 monitor PC. I will keep the OLED monitor as my center monitor while the other monitors are LCD monitors. Any game that forces me to letter box or window the game, due to inflexable native resolution support, gets moved to one of the cheap flaking LCD monitors. Meanwhile, I run a simple screen saver in the background on my desk top to reduce pixel burn in on the OLED monitor. OLED monitors are still very expensive high end displays. LCDs are well established and completely immune to pixel burn in.

CPUs are general purpose processor that do the general calculations and data. If a PC is handling AI algorithms, they are often done in the CPU. CPUs handle the more complex large file handling. CPUs handle the general interactions in a game. CPUs have fewer but massive complex processor cores optimized for large complex logic work.

GPUs are their own specialist computers optimized for complex graphics and physics vector calculations from hundreds of thousands of really tiny simple files. CPUs handle the general interactions in a game. GPUs handle the complex lighting, light rays, fragmentation physics and image 3D rendering. CUDA and Tensor Cores of a GPU are thousands of puny simple processors optimized for tiny random floating point calculations.

Keep in mind, most of these cards are sold to crypto currency miners who run their cards hard nonstop 24/7. They tend to burn through any catd in a couple of years.

That’s a drop in the ocean as far as Nvidia is concerned. That’s a company that moves nearly half a trillion dollars in products every year. 5 billion is chump change
