Just like the title says, is the 2080ti worth the money for seti? Or would money be better spent on 2 older 1080ti's? I considered the 2080, but its power seems about on par with the 1080ti for crunching. I jumped on board the AMD train briefly when I purchased 2 radeon 7's. But after a month of having nothing but an insane amount of issues with them I returned them. Wife nearly left me over the mess I was making in the office and house trying to get those radeon 7's to run without issue no less.

All in all 1,200+ for a 2080ti is somewhat steep and I dont want to throw money at it if I can get 2 of something comparable for the same amount.

Kind of sounds like you have already convenience yourself out of buying it. I would have a hard time justifying a 2080Ti at it's current price tag. That being said, if you can find some deals on 1080Ti, then it might well be worth it going that route. My opinion.

Or 2 RTX 2060s. Or 3 (or 4) GTX 1660Tis.

I'd suggest looking at Shaggies most recent graph to see just what they are capable of, then look at their pricing.

Skip the 1080tis and buy 2 RTX 2070s instead. They will outperform a single 2080ti

You couldn't be more right. I technically already have one for my main rig, but I dont crunch on it. Its impressive, but hard to justify for something that Im not even going to be touching anytime. My biggest hang up on 1080ti's is that they are pushing a few years old nearly and dont want 6 months down the line that they aren't really useful anymore.

How much better would you say 2 2070's will be over 1 2080ti? If only a few percent Id probably still stick with the 2080ti. At this point Im also reticent of more multi-gpu setups due to the cooling factor. The room I have most of my stuff in is insanely hot. I have a 12k portable ac in it (in addition to the house AC), but its running 24/7 and using around 1600watts which is a sizeable amount. Not sure what I can do to get around this outside of not contribute anymore heat into the room & setup.

How much better would you say 2 2070's will be over 1 2080ti?

Roughly 50% more work, and each card uses significantly less power so requires less cooling to keep it's temperatures at a reasonable level.

This is very good info. I think I just may roll with the 2070's! Appreciate the help my friend!

Out of curiosity how do you manage 64 cards per setup? Where do even put all this at? How do you keep them cool? Id like to do more cards per box, but sheer electrical issues are a hindrance at this point. Did you have to hire an electrician for an extra panel. Just so damn curious.

The easy answer is that I’m not.

The most powerful system has 10x RTX 2070s. Another has 6 GPUs and another system only has 2 GPUs.

I have a custom boinc client that presents that the system has 64 GPUs so I can cache more jobs to help cover the long outages. It doesn’t make the systems faster or anything, just keeps them busy longer when the project goes down.

But even managing the heat and power consumption from 10 powerful GPUs can be a challenge. I have the system set next to a large exhaust fan sucking the hot out directly outside. It works well. If you want to run a lot of high powered systems, proper ventilation is the most effective.

I run all the systems on a single 30A 240v line, which was already there and repurposed. and have some overheat to spare.
