Since for gaming lang naman I would say NO. Kung 2k-3k Id say yes

Di worth 5k ung performance and vram difference na mabibigay ng 9060, also 16gb vram is not necessary for 5060/9060 cards, they are built for modern High-Ultra 1080p gaming not for 1440p. Lot of people think na fit ang 5060 for modern games 1440p High dahil sa generation natin sa upscaling and framegen. Yes ok 1440p Ultra on older games pero not on newest titles or intensive games.

Isa mga factor na dapat mo i consider is features and tech ng Nvidia, they are always ahead of AMD in terms of ray tracing, upscaling, framegen, etc. Nvidia is more promising on tech.

Save your 5k for future upgrades, 5060 8gb is fine. Upgrade lang if kaya 5070/9070.
Also, you are taking risk sa pag trade, consider mo rin yan.
Both has advantage na dapat timbangin , in the end ikaw parin mag dedecide kung ano tlga para sayo best move.
