Help me decide if I made a good graphics card purchase

Current setup

RTX 3060 8gb vram

32gb ddr4 RAM

2TB SSD

Ryzen 7 (2 year old cpu I can’t remember the specific model)

Today, I purchased an RTX 5070 12gb shadow oc for $400. A local was selling it and had a receipt where he brought it in December and only used it for light gaming. It came in the box with the original protective shielding and all.

I have a 1440p 120hz ultrawide and a 4k OLED 120hz monitor. I’m a gamer and play a bit of everything.

Did I make a mistake purchasing this? I’ve heard up and down things about the 50 series and I cannot afford a $1000 graphics card. Hearing so many up and down things has made it difficult to justify the purchase.

Thank you in advance.
