Simple swap of the CPU/GPU when Rocket lake/Ampere arrive if you really need more performance.
A high refresh, g-sync, ultrawide monitor - sweet spot between 4k and 1440p.
You've got german engineered case, austrian engineered cooling - peak performance right there.
Motherboard with top tier VRM, I/O and audio.
Basically the fastest CPU/RAM/GPU combo. Could theoretically get a bit more performance by swapping to a 2080ti, but it's not really worth it.
Configured as is with 6x Noctua NF-A12x25 fans (2 on the CPU cooler), removing the stock fans, it would be virtually silent within that case assuming you tune the fans to never go above 65%.
Optical Keyboard/Wireless Mouse w/dock combo - luxurious.
A PSU and case that will last another 8 years no problem.
Air cooling for zero hassle maintenance.
There's little RGB, basically just the GPU, but that shouldn't matter.
No prices for the keyboard or PSU, but they'd bring the total cost to approx. $4k when factored in.
As for headphones - they're a hugely personal pick, I personally use V-Moda Crossfade M100 masters, with a Schiit Hel AMP/DAC, but you should let your father choose. Same with mouse to an extent.
For those recommending AMD builds - the guy just games, an i5 10600k beats every existing AMD cpu at gaming stock, so quit with the workstation recommendations.
