Adding a new 2080ti to my present one-what SLI to use?

Hey Lads,
Over Christmas, when I first got my 2080ti, my choices were limited since everythig was sold out, so I ended up with a Zotac 2080tiGeoforce RTX. Can't really complain about it, it's been good. nut now I want to add another 2080ti, I guess possibly another 2080 ti (do I need to, any know or can it be ANY Geoforce)? i want to get one that's already overclocked and sped up and has "amp and extreme writen on the box.
I want to order it from amazon tonight, but not idea which 2080ti I can get and also which SLI I can use. I have one ZOTAC SLI but it leaves only 1 space, when i think I need 3 or 4 for heating purposes. Anyway, ANy advice from someone who has done it would be really appreciated. Have epnt all afternoon on th net and all i keep finding is cotradictiory ****. thanks....

not sure if I made this clear-- if one of my GPUs is Zotac, mustthe other be or can i get... a NVIDIA founder's edition Barring that, really wantt o get an "amp" and "Extreme." and does anyone know if I NEED to use the friggen ZOTAC stuff? I mean, I'd sort of like to as compared to some of the other stuff (for example, the ASUS thing is over $100). So, if anyone has any advice, I'd love to hear and would realy look forward. thansk...

You don't need an exact match, but it's going to run at the speed of the slower card.

Intel i9 9900K Coffee Lake @ X8 5309mhz (+47.5%)
AMD FX-8320 Vishera @ X4 5022mhz (+43.5%)
Intel i5 4690K Haswell @ X4 5013mhz (+43.2%)

WEll, thanks for the response mate, only one, I presume since people think I'm a new when they see "3 posts" and don't realize i'm been posting her almost 3 years and just lost my ID somehow. So, as far as the SLI, any ideas on what to use? Zotac makes one for about $40, ASUS makes a much expensive one as does MSI. I'm completely torn on this.
also, have seen articles telling me that having 2 2080 ti cards is just wünderbar, and others that say it's ****e and it basically just slows you down essentially. Have a hard time believing the song contention and think it's mostly just jealous look who cannot afford it.
Any thoughts fro ANYONE or any links to good articles on this issue from the (VERY) few journalists left with any integrity. Also, would REALLY, REALLY appreciate hearing from someone who had already done this with 2 2080 tis. Thanks mates....

addendum- by geforce, do you mean the founder's edition? IDK, according to every test, the fridge ZOTAC overlocked and "amped" comes out ahead in a speed test. Though not sure how much of this even matters. you make a good point about it reverting to the speed of the slowest card, but if i spend this afternoon overclocking my Zotac, that should make a difference no? Additionally, you're getting to extra memory and other aspects of having a second GPU. I know, it won't be useful for EVERY game but-- esp the ones that have the "c" plug for VR-- it will certainly prove useful in the future, no??

doesn't really matter, just don't add a blower & sync their bios if the base & boost clocks are different.

it would be easier for you to just add another zotac, but I personally think they're garbage. The 2080 i got performed like a potato, n was thermal throttled 90% of the time due tothe blower not having a jet engine setting.

This is coming from someone who has owned more multi gpu setups than probably 97% of all users on here. But I would try my best to get a matching card. I know you can run different cards of the same gpu core but i have always had better luck with matching cards. You will also need the Nvlink Sli bridge for your boards spacing.

I said Geforce because you called it Geoforce twice.

SLI yesterday, today, and tomorrow will forever be a silly idea. But do what you want.

n by the time NVLink is actually a thing, working in DX12, 2080ti will be an antique.

better off dropping that 1.3k on a new stereo for your car. You'll get exponentially more enjoyment out of it.

-From a Current, and long time SLI user, to a potential dabbler... if you've got it to burn like that, for sure go for it, its great the 10% of the time it works. However, if its this or that. Get the subs.

My advice if you want to SLI (Nvlink) make sure both of the GPUs are the same PCB width because the Nvlink is a hard bridge and is not flexible like some SLI bridges. The Zotac RTX 2080 Ti Extreme is incompatible with your card (AMP Edition) because its PCB is wider. This oversight is easy to make and get you screwed.
Only cards that will safely be parallel to your card to connect the Nvlink bridge are reference cards.
