Hi all, currently my pc is about 6 years old atp, and I'm looking to upgrade it to primarily play borderlands 4 and some other demanding titles

cpu: 2700x

gpu: 2070 super fe

cooler: kraken 280 mm aio

ram: corsair vengenace (3600) 2x8

mobo: rog strix x470f

psu: corsair rm 750/850 (need to double check, but probably 850)

ssd: intel 1 tb 660p nvme

monitor: 1080p aoc 27'' 144hz

What is the most effective way for me to upgrade my build? I have a budget of around $600-$800, and I'm looking to buy a 1440p monitor. I'm open to new and used parts as well, any suggestions?
