To OP, I would suggest it's not worth the upgrade if you are staying at 1440p and already getting good results at ultra settings for the games you play.
Have you checked exchange rate recently? 🤔 USD900 =/= AUD900 or anywhere near! Exchange rate is around 1.60 and that will bring 4080 12gb version cost to AUD1,440 when converted with advertised retail cost in US $899.
Now, lets add extra costs of import/export taxes (both sides) and cost of following Australia Consumer Laws and then on top of that any extra margin retailers there might want to have. That 4080 12gb priced @ AUD 1,500 seems perfectly fine. I would even say you are lucky to get it so close to retail price unlike in US where scalpers will end up buying most of the stock and then resell at higher price.
Bruh why are you teaching me about exchange rate? first, I mentioned $1500 for 4080-12, not $900. Why do you think I did that? Second, I said ‘roughly’, we don’t know until it is available but rough estimation, based on current currency rate, it can be $1400, it can be $1700, nobody knows but retailers. And they’ll have mediocre cards and good premium cards priced differently, that’s always been the story, 3070 Ti today, here in Aus, some are available at $800, and the premium cards like Rog Strix sold at $1100, and still selling well. Lol
And no, you don't need to teach me about import/export taxes and consumer laws either, that's common knowledge, added into consideration. If any, retailers within this PC industry, are not very reliable in term of following Australia regulation. Ain't like general major players in electronic stores such as JB Hifi where we can return, claim warranty headache free, even the best PC stores out there will try to get away avoiding RMA and make things complicated. I tried to return extremely loud PSU, 1 day old, they said it's normal for PSU to have coil whine LMAO, so I return it at "change of mind" policy instead of RMA scheme, cost me $49. Get another PSU from another store, been using it for 2 months, not a noise. Aussie consumers protection is great, but it only applies to certain major electronic stores, PC stores in Aus, based on my experience and what I read online, acting per US standards LMAO.
So, let's focus on the main topic here, performance upgrade Vs money spent ratio. And my original comment is potentially the best out of this page, already LOL.
I wrote US price better than Australian price simply because, well,
4080-12 was advertised for only $900, and over there my TUF 6800xt OC, still $750-800. US Ebay listings for used 6800xt priced at $600-700, that leaves them option to top extra $300-400 if sold, for MSRP 4080-12. Currency rate? It's only extra $500, to get the upgrade, or if wanted to get 4080-16 that's probably cost $1300 later on, ex 6800xt users that sold their GPU for say $600, need to add extra $700, in AUD, that's extra $1000.
Us in Australia, If I were to sell my GPU now, best best I would get is $800, and to get 4080-16, I will need to top around $1400-1600 extras. That is around 850-1000 USD. Now, you also understand, why GPU prices in AMERICA considerably much better than Australia
OH, and Australia too, just like the rest of the world, got all these resellers buying out everything that's highly anticipated by people.
However, I believe it's not their time now, let alone for 4080-12, no one really anticipating that particular GPU, unless we own extremely outdated GPU. For the money needed to spend for the upgrade, even people with 2080ti or 3070ti may just skip that thing. If, we own super outdated GPU, or building new PC from scratch, or moving out from console, then yes, 4080-12 worth the money, especially here in Aus, it's $700 cheaper than the 16gb counterpart at least. LOL. and for 4080 16gb, it's considerably high rollers rig, that breaks the price of current 3090Ti both in the US and in Australia, how many people today willing to pay a 3090? let alone 3090 Ti? Not many, because not many people have that kind of many for "gaming". and if these scalpers get them, try to sell them at 1500 USD? LOL, they'd lose money. No one are going to get them at that price, too much.
