Yo, for 1440p speed‑demon mode you wanna go RTX 4070 or 4080, 16‑32GB GDDR6X is sweet, pair that with an AMD Ryzen 9 or Intel i7 13700K to keep the bottleneck low, and throw in at least a 32‑bit DDR5 kit at 6000MHz – that keeps the data flowing. Don’t skimp on the cooler, a good AIO or a decent air cooler keeps temps low, so you can push higher clocks. And yeah, 650‑750W PSU from a solid brand, keep that airflow in the case. That’s the sweet spot for buttery smooth 1440p. Game on!
