Whether to upgrade from an RTX 40-series to an RTX 50-series GPU depends on which 40-series card you have. If you own a RTX 4090 or RTX 4080 Super the performance gain from the RTX 5080 is real but not transformative. If you own a RTX 4060 Ti 16GB the jump to a RTX 5070 is substantial. DLSS 4 Multi Frame Generation is the feature that tips the balance for competitive gaming.
Two GPUs fighting for the same sub-$350 budget targeting 1440p gaming. The RTX 4060 Ti 16GB has more VRAM — 16GB versus 12GB on the RX 7700 XT — and draws dramatically less power at 165W versus 263W. The RX 7700 XT leads in raw rasterization by 5 to 10 percent at 1440p due to its higher memory bandwidth. With DLSS 3 Frame Generation, the RTX 4060 Ti 16GB advantage in supported titles becomes significant. Within $30 of each other buy the RTX 4060 Ti 16GB. Never buy the 8GB RTX 4060 Ti.
The RTX 5090 draws 575 watts and that changes everything about cooling and powering your build. You need a 1000W ATX 3.1 PSU, a high-airflow case, multiple fans, and attention to room temperature. From someone who ran 55 cards at similar combined wattage.
