These replies are seriously unhelpful. Yeah he could have provided a bit more information but it's not hard to make a basic recommendation. Here you go:
- 1080p High: 1650 Super/5500 XT 4GB ($350)
- 1080p Ultra: 1660 Super ($450)
- 1440p High: 5700 ($650)
- 1440p Ultra: 5700XT ($750)
- 4K High: 2070 Super ($900)
- 4K Ultra: 2080 Super/2080 Ti ($1300-2000)
If you want 120/144fps then you should probably jump a full two classes up.
Cheers, it's actually really helpful and supported what I've learned elsewhere.
