The 5090 could be released in 6 months, forget about the 40 series.

Add at least an NVMe for installing Windows and software programs. Do not use mechanical hard drive for Windows.

The B series board might not be good enough for the Ryzen 10,000 series, but 7800x3D is good, but playing at 1440p it’s going to use more GPU than CPU, but 7800x3D is still exellent.

You got solid reasoning in all that you say.

Burn-in is not such an issue due to pixels auto adjusting/moving, so te same pixels are not always on.

I don’t have experience with ultrawide but it seems that some enjoy a curved ultrawide to bring the sides in more.

I’m not sure of the connect between nano IPS branding and LG, but I will always say IPS over VA. TN and VA are low grade compared to how much the price for IPS has dropped, that’s why I believe anything lower than IPS technology is not an option for buying, but do what works for you since it’s your money being spent.

VA is good for high framerate, not colour or picture quality. It’s your choice, I will always suggest something between IPS and OLED, never VA. If you can’t do a 21:9 nano IPS, get the highest IPS with Adobe colour rating that you can afford.

No, because of the game mechanics and the graphics, I can’t tolerate it anymore.

Medal of Honor 2010 reboot and Call Of Duty 2.

I would suggest the Aorus Master board for long term UEFI updates for future CPU releases.

If you care about future CPU releases in several years, spend as much money as you can on an X670 board. I’m not convinced that the best B650 board can support in 4 years a 16 core processor with future designs, cooling requirements, and provide enough power.

Seeing that Ryzen 8000 is laptop, so the next one will be 9000, if you want a Ryzen 9 10000 or 11000, get something like the most expensive Gigabyte X670 you can buy for future CPU designs.

Buying Radeon 7000 is fine, you can upgrade that in a couple of years and it’s only a 10 minute job to change GPU and run DDU in safe mode.

Thank you for the generosity, that’s wonderful of you to do. There’s no games of interest to me on that list, but thank you for doing that for others.

Do whichever one or 2 you can afford but upgrade to a 5700x, add an SSD, and 32GB for extra breathing room for Windows
