Hi Foxcatcher,
think Haz123 has covered everything (and thanks Haz123 for showing my rig
). All the rigs will play the games you want and more than enough for homework etc. All the cpu's are more than enough, with gaming being bottlenecked by the gpu, not the cpu in a lot of cases. If you want to improve gaming performance then it's the gpu you need to look at. For nvidia the 3000 series cards go 3060, 3060ti, 3070, 3070ti, 3080, 3080ti and 3090. For AMD 6600, 6600XT(sits between 3060/3060ti), 6700XT, 6800XT 6900XT. Haz123 has the 6800XT which is comparable to my 3080, uses less power I think, but doesn't perform as well in ray tracing and misses out with DLSS(also cheaper(if you can call it that) than a 3080 by quite a bit at the mo from looking). AMD now has FSR which will give games a framerate boost, and as AMD supply the gpu's for PS5 and XSX, I would think a lot of games will have it implemented in the future. If you want 4k gaming, then you have to look at the 3080/6800XT I would say, but for 1440P gaming I'd go 3070/3070ti/6700XT(pref 3070ti for me), and the others for 1080p gaming. Going for an ultrawide 1440p monitor though will require a lot more pixels to push, hence why I went for a 3080, though sure a 3070ti will cope
My build as a guide below. I built my rig so I could work from home and game. I'm using a 1080 monitor at the mo which was given to me until I can save up for an ultrawide like Haz above, but just downloaded Control and with everything on high with raytracing was getting 100/110fps, with dlss that jumped to 150/170fps...minecraft got over 1000fps while underground with 99%fps over 400, so gaming not a problem for me.
Waking from sleep, my pc is up and running quicker than the monitor, as when monitor wakes my password screen is already up, and I'm up and running as soon as I type it in..this will be down to the nvme rather than anything, and don't think you'll notice any difference whether you drop to a pcie3 nvme either. I'm not expecting to have to upgrade for years, as the performance is way more than I need

As for Intel 12th gen or ryzen, for your son, I'd stay away from the 12900 or 5900X and above. The extra cost doesn't justify the performance gain in games, and the productivity performance wont be utilizes either for homework etc. For Ryzen, new chips will come out Jan next year with 3D v cache supposedly giving a 15% jump in gaming performance, but that will be it as they transition to AM5 platform. Intel, I've seen no reviewer recommend the DDR5 as the cost is more than double DDR4 for on av1-3% gain in gaming performance, so you'll be looking at a DDR4 mobo. The motherboards are also more expensive than the Ryzen boards also as they haven't released any b board equivalent yet, so whichever route you go, next upgrade in future for either platform will require a new motherboard etc.
In states, microcenter has dropped the price of the 5800X cpu from $450 to $300, just after intel release. If similar thing happen over here, that's the route I'd go. It just depends whether price drops get reflected in prebuilds or not
Oh, if you got for the build Haz has, get your checkbook out
. Full on watercooling. Looks awesome though
