Upgrade recommendations

[mellow yellow]

So i'm looking to upgrade my gaming pc but its been a while since i researched anything.
i'm looking to play gray zone amongst others, EAFC 24, fortnite, cod etc. i have also dabbled with sim racing, iracing, assetto.
My current set up is getting a bit dated:
Fractal design meshify c tower
b450m mortar max board
Ryzen 5 3600
2 x 8 GB DDR4 3200 (1600Mhz) corsair vengeance
Nvidia gtx 1660 super

ideally i would like to future proof for the next 2-3 years with a budget of £700 - £1000

I could recoup some costs by selling the replaced parts.

I'm very out of touch as ive not really kept up with things since i did this build 3 years ago.

All help and suggestions would be greatly received.

also, forgot to ask, what is your exact psu make and model? (very important, especially as you are now moving up to more power hungry components)

Seasonic Core Gold GC 650 650W 80+ Gold PSU/Power Supply​

What resolution do you game at?

1080p I could go up to 1440.

Do you have an ultrawide monitor? If not, you will benefit in these games.

No not worth the cost for me really.

Sorry to drag this one up again but a divorce got in the way I still have the existing set up. But spending a lot more time at my PC again.
Do the above recommendations still stand or is there better out there for the money?
1440p would be preferred now.

So i'm revisiting this again.
I'm ready to upgrade as my pc just isnt handling the games i play very well now, mainly Delta Force.
I would prefer to upgrade with plug and play on AM4 just for ease but i am open to an AM5 build and keeping what i can, like just the PSU?
I see ram is mega bucks now!

Budget is £1k but not to strict.

Current set up reminder:
Fractal design meshify c tower (does this limit my gpu size?
b450m mortar max board
Ryzen 5 3600
2 x 8 GB DDR4 3200 (1600Mhz) corsair vengeance
Nvidia gtx 1660 super

Any help would be greatly appreciated
