I need help choosing components

Hello everyone this has probably been asked before but I couldn't find the information I needed so I decided to just ask.

So this will be my first ever higher end all brand new parts build and I'm really cautious to what I'm buying because I've never had such expensive parts so i need help choosing a motherboard and a gpu I've decided on a 9950x3d cpu and I was going to buy a AsRock PG Nova but after a quick research it turns out it kills the cpu and even if it's resolved I'm still not risking it after that I looked at a couple of motherboards and most of them have issues some bigger than other so my question is what is like the most reliable AM5 board that has the least issues and least failure rate and has good features and good perfomace if there actually exist one I've seen alot of people say that the x870e that i was aimed at buying is not worth it at all and if its true that's good for me because I don't want to spend a ton of money on a motherboard.

And for a gpu i want to know if the 5080 is worth it or i should just buy a 5070ti I'm planing to overclock not alot because im not that good so with like a small overclock will the two cards have similar performance or the 5080 is like alot better and also what brands to look for and to not look for because I've heard that some brands lock their cards some charge alot more just for the brand and have no actual performance gain others have problems with the fans rattling breaking ect. Any help will be much apriciated
