The card can be bought with capacities of up to 512GB, so we should not worry about recording very long footage with our action cameras while on vacation or during workouts.

CPU Cooler: Corsair H100i GTX

Video: XFX Radeon RX 5700 XT 8GB GDDR6 RAW II Ultra

Power Supply: Cooler Master 850W

SSD: OCZ Vector 150

Case: Cooler Master HAF 922
