Thank u! I appreciate it a lot!!A 1660 Super, on average is probably looking in the +25% FPS increase over a 1650 Super.... It does tend to command a similar increase in price.
Whether that is 'worth it' to you, is entirely up to you.
As for 650W, that's going to depend on the specific PSU in question (make/model) and the balance of your system components... but generally speaking, a decent 650W unit should be plenty for a system with a 1650Super or 1660Super.
Sounds good to me m8I think that the GTX 1660 Super is the best 1080p card for it's price / performance. That card was recommend a lot on this forum in the past months.
