Issue

My GPU and PSU were damaged due to frequent brownouts in Albay, so I need to replace them before the system just sits unused and gathers dust.

Planned Upgrades

• GPU: XFX Radeon RX 9060 XT 16GB
  • Also considering RX 9070 XT, but that requires more budget
• PSU + Monitor: Still undecided — looking for best value options

Initial choices:

• PSU: ASUS TUF 750W
• Monitor: NVision 27” / 34” Ultrawide (200Hz QHD, 1500R – MG34UF20)

P.S.
-Yes, I "was" an ASUS TUF fan boy until I've experienced ASUS' very bad customer service.
-I'm planning to build / transition to MSi for its better overall "value".
-Framework as laptop in 2028 if the prices drop for the masses, fingers crossed.
-Pictures of my PC are to follow, once I've returned to Albay, maybe around this June.
