As always, the key to your purchase decision lies in your specific requirements and budget. The RTX 4070 Super is the better value-for-money proposition here. So, if all you're looking to do is play 1440p games comfortably with the best graphics possible, the RTX 4070 Super will do the job while also saving you money.
However, if your demands extend beyond gaming or if you're gaming at a higher resolution (or on an ultrawide), the RTX 4070 Ti Super is the better choice. Sure, it's going to burn a bigger hole in your wallet, but it's the better long-term choice if you're looking to get the best performance possible while still getting the most for your money from Team Green.
