Fah performance is really dependent on the particular unit being processed. They can use a different mix of compute units be it fp32 or fp64. 

F@H is almost entirely FP32 is what I've been told. I'm not aware of any cores having ever used FP64, though some people claim a few projects did for specific simulations.

I was thinking of eventually having dual 3090s. Not connecting a 3090 to a 2080ti.
Early technology details make me inclined towards the 3090 and using my evgabucks to soften the blow. But I'm really waiting on Anandtech.com to do the benchmarking or other source for Folding@Home details. Since I'm waiting on a watercooler card, there will be plenty of info available.

Game benchmarks will be important as well when Cyberpunk 2077 comes out and other games start to target some of the features of the 30 series cards.

I'm leaning toward a pair or 3080 & water blocks

It seems they are referencing the 3090 to a titan level card. Looking at Nvidia's history I believe a 3080ti will emerge eventually after a lot of people had already bought the 3080.

I haven't played a single game that needed more then 9GB of VRAM. And the biggest by far was the new Microsoft flight simulator. Most games end up around 6GB to 7GB at 4k. That 10GB should not really dissuade you for top end 4k gaming.
It's a real stressfull waiting game. I'm assuming Nvidia has the benchmark release dates set at launch time for each card. So at least we'll have some good idea of performance within a few days. Whether Nvidia feels compelled to drop a 12/16GB card in between the 3080 and 3090 really depends on AMD. Since AMD has only teased their announcement I can't imagine they really plan to compete in the super high end. But putting 16Gb on their flagship might force a 3080/3080 Super/Ti with 16GB.
Not that many people will actually switch brands. Hopefully I can control my clicker until a more reasonable card shows up.

The review embargo for 3080 got pushed back until the day before 3080 launch. Generally not a great sign of confidence historically. I know they said there were reasons but still.

The 3090 won't be out for a while.
Also, you can better fold with it, probably in a few months anyway, as they have to benchmark, and test it, to make WUs available for it; so it won't run underpowered. 
 
if you have the mobo and hardware, you can still run the 3090 on the main GPU slot, and run a 2080Ti on the secondary slot, at a reduced performance.
The 2000 series are still a bit comparable, if ran in efficient mode (~1500-1700Mhz, 170-190W)

I have a 7900X on a Rampage VI Apex so both cards are running x16

Looking hard at the 3080 FTW to replace the two 1070's I'm running in one of my systems. Should see a nice increase in Completed WU's with the 3080.

As expected, bots took all the initial inventory. Was refreshing every couple seconds on nvidia site. Went from notify me to out of stock between refreshes.

I dont expect anything less until at least X-Mas.

Why would you blame Bots ?
 
Hundreds to Thousands of customers, pounding F5 ......  EVGA site gets hammered ..........  Demand was greater than supply
 
Third party sellers can get their inventory from any retail channel .....  hey store manager .. I'll give you $100 over Retail for every GPU you get
 
Some stores might even offer employees first crack at any inventory ...  who knows

Cool GTX

The API for the Nvidia store was "leaked" to a bot net.  The same company that does this type of thing for shoes.  They bragged that their customers walked away with upwards of 40 cards a piece.

Humans can almost no longer buy high demand products online.  Even reading the threads on reddit, maybe 1 in a 1000 got a card.  Y

when u can get one
 
currently im doing two builds
one for friend and we are waiting on intel 10 core and a 3080 for that one
im looking at ice lake x or cascade x 18 core or more and 3090

I'll be honest, the scores I've seen posted and the prices of the new cards have changed my mind and I will be getting some for folding. I will not be an f5 masher anytime soon but when things calm down I will snag up 1 (or 6+).
After mulling over a few f5 complaint threads I am getting a good idea who was hording all the toilet paper a few months back.

I gave in since I was ready for another card to add to my system. Got a 2080 super FTW3 and then will step it up to a 3080 FTW3. Then I don’t have to be an F5 smasher but will have to wait several months.

Well it is not looking like it is worth the 3090 so far.  So know I think it is wait for a 20GB 3080 or see if NVIDIA is forced to do a 3080 TI sooner than later due to Big Navi.  Butt of coarse they will never be in stock with.

I don’t think we will see Ti branding on the 3080 soon. They would have to give the 3090 an equal boost and Ti version. It isn’t unprecedented to do so cause the 1070ti was essentially a regular 1080. I do think we will see a 20GB 3080 and 16GB 3070 soon to do battle with AMD. I just think they will coexist with the lower memory version just like what AMD does. 20 GB 3080 coming in at around $900 for FE and16GB 3070 FE coming in around $600. That would help fill out the pricing structure more but not step on the toes of anything around it.
