Built for both video editing (After Effects and Premiere, eventually plan on switching to Davinci Resolve) and for 1080p/1440p gaming.
I think my favorite thing so far is no matter what can of load I throw at it, I literally cannot get the CPU to exceed 70 degrees and the GPU never goes higher than 69, so looks like my choices in cooling were good.
Only second machine I've ever built, so not a lot to compare to, but comparatively speaking to my old machine it has been an absolute monster for render times in both AE and Premiere.
Also ridiculously fast at encoding/transcoding/conversion batches in programs like Handbrake.
And ofc, has been great for gaming. Only tried DOOM (2016) and Modern Warfare (2019) so far, but consistently 130+ fps on Ultra 1080p or High settings on 1440p.
Also consistently 100+ fps on same settings as above when recording on high quality via Nvidia and OBS programs.
Only problem I had during construction was taking a whole day to figure out the AIO cooler, never had one before.
