So, I have this PC I built back in 2012. It's starting to really show it's age, it's CPU and GPUs are old, noisy, and use a lot of power due to being SLI. It's a 3770K system with two slightly overclocked GTX 670s in SLI While a new CPU is out of the question for now as that would require me to build an entirely new PC, I figured nowadays I can easily get a single card that can outperform my SLI setup and at least keep this system more viable for a few more years before I just entirely build a new one, that way I also have to worry about less heat, power, and noise... as well as freeing up a PCIe slot..... issue is, that my CPU is so old that I worry about a card too new would be useless vs an older one due to bottlenecking. I was originally going to get a used 1080TI on eBay, since from my past experience typically the X80 Geforce of a previous gen still outperforms the X70 of the next gen especially if it's a TI model... but that doesn't seem to be the case this time. An RTX 2070 Super appears to outperform a 1080TI in most cases.... and a new RTX 2070 Super seems to go for roughly the same price that a 1080TI goes for on eBay. Issue is, I don't know how this will effect bottle-necking, I saw a lot of posts about a 1080 (Not sure if it was Ti or not) working fine in a 3770K, and a lot of posts about a RTX 2070 being bottlenecked in a 3770K. Will I still get the same level of bottle-necking from both cards so they would both perform exactly the same anyway? Or would the 2070 Super actually be bottlenecked worse than the 1080Ti on a 3770K and actually perform worse?
