Upgrading the arcade cabinet PC - options?

[alex2005]

I have a Sega Blast City with CRT Emudriver, Windows 11 and the following hardware:

- Intel 4790K
- motherboard Gigabyte B85m-d3h
- Graphic card Sapphire 7850 HD with modified bios for 15khz (connected to the Sega Blast City VGA with a DVI-VGA adapter).
- 24 GB RAM DDR3
- 2TB SSD (x2)

And plenty of emulators with Hyperspin (Model 2, 3, Mame, retroarch, RPCS3, Xbox and several PC Games)

What I also like from my current setup is that I am able to change the boot logo of the motherboard, so I replaced the default Gigabyte logo with a nice and clear Sega Blast City logo.

What I am thinking is to upgrade my PC. I could keep the SSD and the probably the graphic card (unless you tell me there is a  better option), but the rest I would like a change for a less power / noise / heat / consumption and more single core performance, so I was thinking of a Ryzen 5700G or similar. I guess I will  still need an integrated GPU in the motherboard as I'll need to do the W11 and CRT Emudriver setup from scratch.

What setups do you guys have, any recommendations? If you have a modern setup, have you been able to modify the bios boot logo as well? Reading here and there, seems unlikely the case in modern motherboards.

Thanks for the support,
