New PC or just certain specs?

My pc was decent for when I bought it, but few games run properly and I think its just my PC being outdated. I have an RTX 2060, I7 core (dont know how to check gen), and 8GB RAM.

I always was able to run games smoothly, up until very recently were most games I own crash all the time, even games with very low minimum requirements. Such games include R6, Titanfall 2, Battlefield 1, Squad etc.

Just posting here as im planning on upgrading, and im not sure what to get. I may be wrong but i feel like if I upgrade most of my main specs, itl cost almost the same as just getting an entirely new build. Just looking to see what is the standard specs are to buy nowadays, Cheers.
