In short I bought my pc 3~4 years ago, and at that time I just got a entry level kit to upgrade later on (it was a Ryzen 3 with a RX 570). Today Im using a ryzen 5600 and a RTX 4060ti but Im still using the same cheap a520 motherboard (this one: https://www.gigabyte.com/Motherboard/A520M-H-rev-1x#kf) is this a big deal? Im not really having performance problems, most games I can run just fine but I saw in the 4060ti specs that the GPU supports PCIe 4.0 x8, but I dont know if the performance impact is big enough for me to buy a new motherboard, what do you guys think about this? Should I upgrade, if yes any suggestions?

Does PCIe 3.0 x4 kills my RTX 4060ti performance?

Your board has x16 slot and I doubt that running it at 3.0 x8 impacts performance. Hell, it didn't do much even with my RTX 3080.
"1 x PCI Express x16 slot, supporting PCIe 3.0 and running at x16"

OP has an A520 board so it's PCIe 3.0.

Here are a few articles that Wiz did on PCIE scaling....

My best guess is that you will see a slight degrade in performance, like 1% to 2%, which is nothing to worry about.

I use my 4060 Ti with PCIe 4.0 x4 (via Oculink) which has the same bandwidth as your PCIe 3.0 x8 and I have encountered no noticeable slowdowns or performance bottlenecks compared to other 4060 Tis using the full 4.0 x8. You should be fine.
