Question Appropriate CPU to pair with H470-ITX/ac and XFX RX5700 DD card?

I built this little mini-ITX "Golden Fields M3S" rig, and I had an XFX RX5700 "DD" model which needed a home, and I wanted to get it mining, right away. So, I semi-miraculously managed to wedge it into the case and get it and the two PCI-E cables plugged in.

It works, but then I was thinking of selling it as a 1440P gaming PC.

So I'm thinking, of upgrading the CPU too. Would an i3-10100 do (4C/8T), or should I go 6C/12T (I think?).

What 10th-Gen CPU would be an appropriate match for an RX 5700 non-XT.

Note that mobo is an H470 ASRock mini-ITX board with built-in AC wifi as well as 1GbE and 2.5GbE ports, and dual M.2 NVMe. (Primary populated with a 256GB NVMe.)

Core i5-10400 or 10400F

Can't OC, so that rules out 10600K.
i3-10100 or 10100F might be too stingy.

5700 actually is almost as fast as the 5700XT to my understanding, you just need to OC it a bit. I agree a 10400F makes sense though.

Re-visiting this. (This may indeed be more appropriate for the CPU sub-forum).

Would it be better to get an i5-10400F on ebay from a reputable dealer for $159.99, or an i5-10400 non-F (WITH iGPU) for $179.99 from Newegg?

Or would it be better to wait for 11th-Gen/Rocket Lake? I read on vidcardz that the quad-core and lower 11th-Gen were just going to be re-branded Comet Lake 10th-Gen parts, so no different than current-gen. I don't know where the 6C/12T CPUs fall in that spectrum.

My concern, is having the iGPU, should the dGPU fail, and the user need a backup to use. If the price difference isn't substantial, then perhaps I would want the iGPU. Plus, can't you use QuickSync for video-encoding if you're doing game-streaming, to offload from the primary gaming GPU? Or does that even make sense these days with gaming GPUs being so powerful, and AMD cards having their own Video Codec Next or whatnot?

A Radeon RX 5700 series won't make Rocket Lake matter much.

On dedicated GPUs, the video engine is separate from general shaders. It doesn't affect the gameplay much.
For NVIDIA NVENC:
However, Intel QSV, the Gen 9.5 Kaby Lake revision, and AMD VCN haven't been famed for good H.264 quality. The Intel QSV Gen 12 Tiger Lake revision to be featured in Rocket Lake might be good, but testing is scant because there is no desktop product for the 'streamers' to test.

The only place where RKL-S will benefit you is in the 1% lows. Average framerate will always be defined, however, by your GPU's capabilities, and 5700 and 5700 XT/RTX 2070/2070 Super are boarderline GPUs for GPU limited gaming. Everything above those GPUs NEEDS properly fast CPU. Especially for high refresh rate gaming in 1080p. Not so much for 1440p.
