I'm in the process of planning my first PC build and being a noob to the PC building game I was wondering if there are many reliability issues with used parts. For example, going with a used graphics card would allow me to get a card with higher performance than buying one new. I'm specifically looking at either a new RTX 2070 or a used GTX 1080Ti. If anyone knows of any posts already talking about this topic could you point me in that direction?
