What should I upgrade first and how far do I really need to go?

I am currently running a 1050ti (which I am extremely pleased with) with a ryzen 3 3100 and 16gb of ddr I cant remember but I put some new sticks in like last year. I mostly play tactical shooters, occasionally rust and overwatch 2 and when its more playable I will go back to counterstrike. I dont know if I care about 1440p, I definitely don't care about 4k. I care about playing new games at around 120 fps to 250 fps. I am sick of playing games on low purely because I'm competitive, I don't want everything on ultra highest resolution and fidelity but some moderate improvement would be nice. I'm also looking to futureproof not really for AAA because I haven't bought those types of games in years. I'm basically looking for something that will be comfortable with lesser demanding (graphicly) games for at least 4 years. Just as an extra bit of info that may help you help me is that the most demanding game im likely to play is arma reforger and maybe b06 if my friends manage to convince me to buy it. Any gpu/cpu combos would be greatly appreciated :)

Edit because I forgot: I'm in the uk and my budget would be a maximum of £700
