New graphics cards like the 4070 Ti are very expensive — more than they've ever been in the past, in fact. This, in addition to the fact that GPUs are also harder to find in stock than they used to be, makes cards from previous generations attractive alternatives.
While older GPUs like the RTX 3070, 3070 Ti, and 3080 won't offer the same elite 1440p and ultrawide gaming performance you'd get with the 4070 Ti, they're fairly easy to track down and are much more affordable, too. If you're on a budget or a tight timeframe and you're okay with sacrificing some performance, taking advantage of the best graphics card deals for an older GPU is a fantastic idea.
With that said, we recommend sticking with the 4070 Ti if you're looking for an experience without compromise. It's the most powerful 70 class card that NVIDIA has ever released, and it's perfect for pushing high framerates at max settings with a 1440p or ultrawide display.
