BG3 & TS4 & Stardew Mods girly PC build help!

• New build or upgrade?
  • New build! So exciting! I am extremely overwhelmed with all the information but I just wanna play my games comfortably, I've seen other posts with recs for this kind of request but they're a bit older and a lot of the things are out of stock and I don't know good replacements/subs lol
• Existing parts/monitors to reuse? (List with models/links)
  • I have a monitor that I currently hook up my Macbook Pro with a thunderbolt cable and play BG3 and everything else this way...it definitely is not ideal lol, works fine for Stardew Valley without mods but I've had BG3 for more than a year at this point and quit every time I get to Act 3 bc I can't deal with the lag and slowness and butt quality
• PC purpose? (Gaming, editing, etc. List apps/games)
  • Gaming, some work.
• Purchase country? Near Micro Center?
  • USA..not near a Micro Center
• Monitors needed? (Number, size, resolution, refresh rate)
  • I have a monitor, I think its 100 hz. Really do not want to buy a new one as I like the look of this one and I am attached to it but if its gonna interfere with gameplay with the PC, I would get a new one--this is the one I have: https://www.amazon.com/Samsung-C34J791-Ultrawide-Thunderbolt-LC34J791WTNXZA/dp/B07NSJ2LHF/ref=asc_df_B07NSJ2LHF?mcid=d3fcbd8e8f583fb393cbb94283c237e2&hvocijid=16254423284496871845-B07NSJ2LHF-&hvexpln=73&tag=hyprod-20&linkCode=df0&hvadid=721245378154&hvpos=&hvnetw=g&hvrand=16254423284496871845&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9003659&hvtargid=pla-2281435177818&psc=1Budget
• Budget range? (Include tax considerations)
  • $1400 max, I would of course like to spend less but I'm also trying to not be annoyed while I am gaming and want something that runs really well
• WiFi or wired connection?
  • WiFi
• Size/noise constraints?
  • Doesn't really matter, I can make size work. I would like it to be quiet if possible, but that isn't a huge deal...I just wanna play my games comfortably with no lagging and nice graphics
• Color/lighting preferences?
  • White, maybe some pink. I do like the Fractal North (White w/ glass) but other cute cases would work. I even looked at the Nyanners collab with Ironside but not sure if I should commit to an aesthetic or if I should get something more plain that I can customize and change when I would like to.
• Any other specific needs?
  • No, please help me, I just want to play my games happily lol bout to enter act 2 in bg3 and I am so fed up

Thank you in advance! Any help is much appreciated!
