What's your most expensive gaming purchase ever? (And was it worth it?)

[curl-6]

For me, it's when I recently upgraded my gaming TV to an LG OLED which was around $1000 AUD, or $718 USD, cos the old one died.
It's actually a $2000 TV but I got it half price cos it's a 2025 model that they were clearing out to make room for the 2026 models.
Definitely worth it, games look phenomenal on it.
