Quick Answer
If buying new, the RTX 4080 Super replaces the RTX 4080 at the same price with 5-8% better performance. Always buy the Super. If you already own the RTX 4080, do not upgrade - the 5-8% gain is not worth the hassle and cost of selling and rebuying.
The RTX 4080 has been discontinued. The RTX 4080 Super is its replacement at the same MSRP ($1450 AUD). There is no reason to buy the original 4080 when the Super exists at the same price. You get free performance.
Selling your 4080 and buying a 4080 Super would net you maybe $50 after fees, plus the hassle of selling and buying. A 5-8% improvement is imperceptible in actual gameplay. Wait for the RTX 5080 instead.
