This era lets you carry a system with a real cheap CPU. In fact, I'd consider the 3600 still mostly viable with something like a 4070 Ti Super (it was on sale for like $550). Optimal and capable of its full power? No, not in CPU bound titles but it doesn't need to be with a 144hz monitor in a GPU-bound market. It's still a good 1440p build and more capable than a cheap GPU.

It's a strange, very situational thing, but if you're carrying a borderline CPU like a 3600/8400F/i5-9600k/5500/10400F and plan to throw in something like an 8400F/7600x/9600x down the line and ride it I think it's a totally viable path. On the same note, at 200 Euros probably not (you could probably throw in something like a DDR4 14600k for $300 if you already have the RAM). As someone who has done it.. I'd probably value it as high as $100-$125 USD with the current RAM shortages. Mainly if I was super budget-restricted and force to make a choice between a powerhouse GPU on a dead platform that can carry my existing bad CPU for a couple years or choosing a lower-mid GPU like a 5060 & a 5700X/5800x/5900x/5950X.

Mostly, I'd consider it a budget-restricted thing. Otherwise, it might come in handy to extend a CPU's life by a couple years down the line. I'd probably always pick the GPU > CPU if I were on any

Obviously, frame generation does lead to a slightly worse experience, isn't a guarantee in every title, and is non-optimal.. But it's usually single-player AAA titles that push the limits anyways and I'll take frame gen in a non-competitive experience.

By all means: I am a considerably cheap builder who usually intends to upgrade when I feel something is becoming flat up becoming so inconveniencing that it's no longer capable or when my used parts can leapfrog me to a drastically better platform for a no-brainer price (I did with a 5600 AM4 to AM5 build for $90-110). But I totally understand people wishing to mount as few CPUs/motherboards infrequently as possible and don't want to mess with the used market regularly. For me it's just fun.
