Not sure where you’re looking... same prices on eBay...

4k60? Sorry, now that HDMI 2.1 is a thing, 4k120 VRR or bust.

Unfortunately not here. The pricing of the 3090 is confirmed to be $ 2429 in Australia... We always get the short end of the stick when it comes to prices for new hardware or anything for that matter compared to other countries.

According to my currency converter app, that works out as £1334.63. Which is cheaper than what we in the UK pay at £1399.00!
Short end of the stick my arse. And you get a beautiful country with beautiful giant spiders! But tbf I’ve heard that your cassowaries can be quite ferocious..

Yes cheaper for you but not for us. You simply cannot compare apples to apples. The cost of living here is significantly more expensive and higher than many other countries.
In saying so, I do love this country & yes I fully agree it's beautiful.

What I’m concerned about is that the 3090 might not be the Titan.... Nvidia is notorious for releasing another card a few months after that makes their initial flagship irrelevant...
Now...the 3090 kills the RTX Titan - but will there be a $1000 3080Ti that makes the 3090 irrelevant... or will they release a $3000 Ampere Titan that blows the 3090 out of the water?
They may well do, but I don't think it would be that much better than a 3090 (much like the Titan RTX is only marginally better than the 2080 Ti) - the full GA102 appears to have 84 SMs, whereas the 3090 has 82. So clock-for-clock, only a 2% performance difference. Even with a clock increase, it would only be a few percent (less than 5?) better.

Yeah... I'm hoping the 3090 is the Titan... but still worried about a 3080Ti that performs almost identically for far less...
I think there's good justification for Nvidia to drop the Titan branding altogether, especially given that the Pascal/Turing versions were really poor against the XX80 Ti versions. Looking at the relative differences between the models, it does look like the 3090 is the new Titan:
No problem for me. I have 1200W Super Flower Platinum power supply.I think there'll be both a Titan and a 3080 Ti, there may be super variations, too. TDPs are still scary, though
At least the lower models will get variants with more ram.

hmm idk they used to sell for 1k+ 1200+ USD USA, I linked a sold item, I don't want to encourage anyone to go on EBAY and think everything they see is legit, so I won't link anything unsold. But the prices are only going down. Unless a third party gets a hold of a 3070 or 3080 n finds out it's all bogus.... good times, if I had half a brain I'd sell my ladies new 2060... before the trickle down effect wacks us

Nvidia Ampere is not trouble for AMD.
New XBOX's GPU is 4K60-intended 12 TFLOPS just like 2080Ti or 3070. And it does it as part of 8 core APU of $700 game console. So, $400 big navi at 3070 spec is very achievable.
If the transistors of the 8 cores CPU and IO are reallocated as GPU, 3080-capable big navi is also achievable at less than $699.
So, you better wait for big navi spec before buying 3070/3080.

GPU OEMs should make combo of water cooled GPU and a water block for CPU cooling.
Performance seeker will always install GPU at PCI slot 0 as it is always CPU-direct one.
Additionally, the distance between PCI slot 0 and CPU slot is standardized.

While being in consoles means a lot of unit sales for AMD, the profit margins are generally really low - otherwise the PS5 / Xbox would have to sell for $1000...
The profits come from the mid- high end... discrete cards... and Nvidia has a stranglehold with this lineup... Big Navi keeps being touted by AMD fanboys as the savior - but it’s not out, completely unproven, and will be fighting an uphill battle even if it DOES perform.
Well, we can finally see the core configuration of the RTX 3080:
So it has 6 GPCs, each containing 6 TPCs - except that 2 are disabled, in one or two of the GPCs (depending on how the die has been binned). Each TPC contains 2 SMs, so the 3080 has 34 TPCs in total.
Now, even with every GPC packing 6 TPCs, that would only give a total of 72 SMs, and since the 3090 has 82 - it must either be a 7 GPC chip (84 SMs in total) or a 6 GPC/7 TPC chip (still 84 SMs). It'll be interesting to learn which this is, because the total number of GPCs affects ROP count and geometry throughput.
Each GPC contains 2 ROP partitions, each containing 8 ROPs - so the 3080 has 96 ROPs. If the 3090 is 6 GPC, it too will have the same ROP count; if it's 7, then it will be up to 112. It could have that amount or some could be disabled.
The die is certainly 7 by 6 arrangement:
You can easily see the SM blocks in the die shot, in 4x4 clusters, and since Nvidia's slide clearly shows a full GPU containing 6 clusters (I.e. the TPCs), the GA102 is almost certainly:
The full TU102 is:
The new tensor cores are actually 4 times faster than the old ones, so the reduction in TC count still results in a doubling in FP16 tensor performance. And, of course, the RT cores are considerably more capable too.
It will be super interesting to see what AMD and Intel release against the 3000 series - what a great time to be in the market for a new graphics card! Better still, what a great time to be in the market for a cheap second hand 2080 Super/Ti
