Adding another RTX 3090

[ialikw]

Hi,

 

First of all, specs:

i9 11900K

64GB DDR-4

Gigabyte RTX 3090 Vision OC

1 TB SSD

2TB HDD

PSU: Asus ROG Thor 1200w

 

 

I'm thinking of adding another RTX using NVlink. Will my CPU bottleneck or should I get the new 12th gen i9's?

 

It'll be quite an investment, so I need to make sure if everything works out well in theory lol.

First, SLI is dead, so unless you do actual work on your computer that can leverage multiple GPUs, there is no point in running two. 

 

Second, in the like 2 games that still support SLI, you aren't super likely to run into a CPU bottleneck, but you're likely to run into other GPU issues, like really bad minimum FPS. 

 

Finally, SLI is dead. Just wanted to make sure you got that.

SLI is dead, however, Nvidia has NVlink which is supported on the 3090. Games have to natively support in order to make use of it. 

 

Most of the utilization will be from mining. Better 2 than 1.

ETH mining will be done by June 2022. I feel like a lot of the value of 3090s will drop by then; the only reason they still hold so much is because of them not being LHR-locked, not because of their gaming performance or non-ETH mining performance.

 

It will be of little to no use for gaming, potentially even a negative use, in 99% of modern games. But if you're mining, and are paying a low enough price to be able to make back that cost by mining, go ahead.

The CPU will not bottleneck but the only good use for a second 3090 is for work productivity not for gaming. So if you do 3D modeling or anything else like that than go for it but if it's for gaming don't bother

It has the NVlink connector, though the technology behind it is still called SLI. NVlink has other functionality like sharing VRAM that is disabled on the 3090. Only a handful of games have native support for it, and most of those games are either benchmarks or the support for it is bad. 

 

That said, if you're gonna be mining, it's not gonna matter. If you can get a 3090 for a good price to mine on, sure, but it's not gonna be for gaming. SLI is dead.
