DUAL GPU - GTX 1080 Ti + RTX 3080, would it work? / is it worth it?

[IJD]

Hi everyone,

 

I was planning on upgrading to the RTX 3080. I already own the GTX 1080 Ti.

 

Is it possible to create a dual GPU setup with these two GPUs? And if so, is it even worth it or should I sell my 1080 to cover a little bit of the cost of the 3080?

 

Motherboard ASRock X299 Taichi XE --> might change to MSI Meg X570 Unify

CPU i7-7820x --> might change to Ryzen 9 5900X

 

Thanks to all!

 

Best regards,

I

It would not work for gaming, the cards have no way to communicate and pool resources. You are better off selling it.

Even if it could work SLI is dead and useless. Sell the 1080ti for around 300 - 350. That would be your best option

Depends on what you expect them to do. The 3080 cant do normal sli so its useless compared to a pair of cards that can. 

Id sell them both for a 3090 then you can get another one of those down the line. A proper build.

Thanks! I'll do that. Glad I kept the box and all in case I needed to sell haha. Thanks for the help

Thanks so much! Don't have the 3080 yet, I'm just planning for next year, and I need to upgrade a couple more things so I don't know if I can reach for the 3090 yet. let's see. but thanks for the help!

I have a 1080Ti liquid cooled, I have been thinking about picking up another 1080Ti to SLi, I could get another for £350... Would that be a cheaper upgrade than shelling out over £1000 for a 3090?

 

Ideas for future as at the moment the liquid cooled 1080Ti is preforming well!

Why not just a 3080? Youd need a good game and a cpu to handle two cards. And no one here likes sli as they tend to be youtube parrots and never used it themselves. 

Given the games I play I would still do it but my cpu can barely handle a single 1080ti. 

Then youd have to find another block. Id just leave it be unless you actually have 30 series cards in stock there.
