Equalizer APO with Peace is the way to go on WIndows if you want good parametric EQ. On Linux JamesDSP.

While PTM7950 is great the biggest issue with most modern AMD cards is the mounting pressure of the cooler and that's why washer mod is quite popular mod on AMD cards. Simply changing the thermal compound will often not help.

As per my last comment, I've misread your post. So to answer. Yes, 7900X3D is better than 7900X for gaming while sacrificing slightly the multi-core performance due to lower clockspeeds in multi-threaded workloads. If the difference is 50eur and nothing else is an option, I'd take the X3D still.

I saw 7800X3D vs 7900X3D .... either I'm blind or the post was edited

7800X3D is better gaming CPU than 7900X3D as it provides way more consistent results because it does not need to have to rely on a cross CCD scheduling optimizations. Only get the 7900X3D or 7950X3D if you value multi-core performance for workloads over gaming performance.

A lot of Single-Player games run on Linux well. A lot of especially Multi-Player games don't run on Linux at all because of anti-cheat. If you're mainly Single-Player and are willing to get over some hurdles then there is absolutely nothing wrong with trying gaming on Linux and some games do actually run better on Linux but that does not automatically mean that Linux gaming is better as the experience will vary from game to game. If you're mainly Multi-Player then I can't really recommend Linux for gaming at all unless you're absolutely sure the games you want to play do run on Linux. You can check something like https://www.protondb.com for that. You also need to keep in mind that just because the MP games you want to play right now, they may not run after an update like League of Legends for example when they forced their Vanguard anti-cheat and the game no longer even launches despite being able to run flawlessly for many years before. Best distros for gaming are usually rolling releases but they are also less stable. IMO something like Arch or Fedora will be best but I can't really recommend Arch based distro for newbie.

That's quite good. It's faster than 7600XT

Well, that's quite terrible pricing

7600XT for $400 is a scam... The card is barely worth $300 for the 16GB version. $500 for the 7700XT is also on the higher side but way more reasonable for the performance. How much are the RX 6800 or 6800 XT? RX 6700 XT or 6750 XT are also usually cheaper than 7600 XT while being faster.

So this will use whatever is in the Stream tab which by default will be really bad so you want to change that to HEVC (h.265) preferably with your GPU so for NVIDIA you will choose NVENC h.265 and for AMD there should be something like AMAF h.265. MP4 is just a container it has nothing to do with quality. MP4 has a disadvantage that if your recording gets interrupted for example by random restart or something, the whole file will be corrupted. Something like .MKV should still work until that point though.
