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.
The RTX 4070 Super and RX 7800 XT fight for the same 1440p gaming budget. The RTX 4070 Super draws only 220W versus 263W for the RX 7800 XT — a meaningful thermal advantage in warm environments. The RX 7800 XT has 16GB VRAM versus 12GB on the RTX 4070 Super, which matters increasingly at 1440p maximum texture settings. Within $30 of each other buy the RTX 4070 Super for DLSS 3 Frame Generation. If the RX 7800 XT is $40 or more cheaper buy that. Read the full comparison.
