I think there should be no problems at all with those 2 co-operating but also I guess depends if you looking to OC (Overclock)?
I'm myself team red (AMD), so probply someone with more experience with Intel should share their wisdom and knowledge
First of all, thanks for your comment. I never used AMD until this time. I actually don't think, too. I don't know why, but for me, it seems a bit low-quality. I don't know why.
Still, if I go with AMD, what you suggest?
Keep in mind you will need DDR4 ram, also, for this switch. The 9700k is a nice chip, but for the multitasking ability, and upgrade path, I would choose an R7 3700x, for a bit more longevity, vs an R5 3600. The R5 3600 is a great choice, for today, if you want to save some cash, though. Intel 10th gen will be a new socket.
In a more realistic scenario, maybe you don't have the fastest graphics card and you're playing at 1440p or even 4K where the game is GPU bound and the performance would be the same
That only rings true if all you ever do is play those games at those settings and never upgrade your video card. This is why many sites will even test at 720p and many people scream how no one plays at that resolution while also showcasing their lack of knowledge.
The faster GPU takes away the GPU bottleneck as much as possible and displays what an upgrade path may look like when you are no longer GPU bound in the game. Also lower resolution helps showcase the amount of headroom still left in the CPU for gaming. If a CPU can't do 100FPS at 1080p, it won't be doing it at 1440 or 4k.

Who still tests at 720p? Anandtech, PCper, GURU3d, pcmag, techradar, etc etc etc, all show benchmarks starting at 1080p
