Building another pc here soon, I am just wondering what GPU to get with it? I know with the release of the 4080 and 4090 cards, and now the 4070ti coming out tomorrow, I just don't know what to do or maybe I should just wait. Right now, I have a 3060 12 GB but some things about my PC are feeling lackluster and I am experiencing poor performance issues on games that are now too far out of my control at this point. So what's my response to all of this? Build another one heheeh

Do I keep my card and just change the rest of my pc? Or should I just include a new GPU in my new build?
