Im in a big predicament

After years of not wanting to pay for it I finally paid $10 for a month of ps plus and I’ve been having a blast, but I have a tv upstairs and downstairs now and i definitely wanted another console but $500-600 ps5 set up is kinda a lot and getting another ps4 would just be kinda dumb I feel, I also don’t wanna keep paying to play the games I already paid for, could I get a reasonable pc for the price of a ps5 instead?, I’ve really only been playing gta lately and my wife Fortnite but Ill probably play more in the future and if available on pc I’ll definitely wanna be able to run gta6 Also btw I am a 100% rookie I am not very great with technology but it doesn’t seem to be too complicated
