what's the minimum i need to run Persona 5 @ a stable 30 fps

i have a GTX1060 6GB and an i5-2400 which i want to upgrade

RPCS3 don't require very powerful gpu.
I clear the game on limited(2.5Ghz out of 3.2-3.5ghz...to reduce the heat)i7-6700HQ(laptop)which is almost the same as your cpu in single threaded performance.

The game was running between 12(a lot of people in the streets)to 60fps in menus(using the 60fps patch)
Battles as far as I remember were always at 30fps or above

Here is a nice list of cpus

The higher the score the better results you will get

PS.My gpu is also 1060 but the 3gb version

cpu is more of a concern for RPCS3. from personal experience, a i5 6600k wont run Persona 5, so i don't think your current cpu would fare well. more modern cpu's should work like 9th gen i5 processors or i7.

also, core count matters

If it supports TSX, that's an even bigger boost. Unfortunately, only a handful of CPUs can use TSX. In terms of recommendation, at least a 7th gen Intel should suffice. I use a mobile i7-8750H and it's been really good with Gran Turismo games surprisingly considering that the series is known to be graphically intense in the post-PS1 era.

I assume a Ryzen 7 should be enough, correct? I'm using a Ryzen 3 and debating upgrading to a 7 some day in hopes I could run Persona 5. This is probably a no brainer but I feel as though I should be sure.

With the recent AMD announcement I would definitely wait for the new Ryzen 5000's to come out and for people to post their RPCS3 experiences with them. It seems AMD will finally catch up to Intel in terms of single threaded performance so it will be interesting to see how well they will perform.

I'm waiting for the first real benchmark tests between i9-10900k and the Ryzen 5900 for my next upgrade
