Really need some advice as to what I should upgrade.

  • CPU: Intel Core i5-11400F 2.6GHz (4.4GHz Turbo) 6-Core 12-Thread
  • GPU: GeForce RTX 3060 Ti 8GB
  • Motherboard: B560 Motherboard
  • RAM: 16GB DDR4 3000MHz (2x8GB)
  • SSD: 1TB Intel PCIe NVMe SSD
  • CPU Cooler: RGB CPU Cooler
  • PSU: 650W 80 Plus Gold
  • Case: Gamdias Argus M1

Those are my specs I have an ABS PC. Basically all I'm looking for is CS2 high frames on 1440p. Right now I'm getting like 140 on 1080. Someone on discord a while ago told me It would be a big job to upgrade it because I need a new motherboard and psu, to upgrade the CPU. So at that point I might as well just start from scratch right?

I'm not the sharpest tool in the shed when it comes to PC building. I'm also incredibly busy working at a hospital. I'm considering buying a new prebuilt, but my friend thinks it's a waste. What say you? Guide me, show me your wisdom, I am but a humble peasant.
