Nvlink adapter worth it for dual 2080tis?

Was going to use for lossless scaling then saw that 2 2080tis in sli beat a 3090 in some games

Just get the 3090
Accomplished-Yam7430@reddit (OP)
it was 2x 2080ti for $600 or $800 for a 3090, in hindsight i should have made 2 builds, then sell them, then get a 9070XT but the watercooling is all in place now :) cant change that

Never thought of building another system to watercolor it, smart

Do you play any of those games? If not then you probably don't want SLI. Current modern games stopped supporting it entirely years ago, that's 3090 was the last consumer card to even support it. If you already have them, using them as a combo with lossless scaling isn't a bad idea, but I wouldn't recommend going oit and buying two cards just for that. If you're looking at buying, just buy one better card.

i tried lossless scaling, but when i reboot, the card with HDMI cord in is being treated as the main, what should i do?

Do modern titles support SLI, I thought that was dead

People use it today to play old AAA titles.

does nvlink make windows treat it as 1 gpu or 2 gpus? because if it was the latter, then games would definitely have to support it
ComprehensiveOil6890@reddit
Nope it ended with 30 series
blind_stone@reddit
Which or what did
ComprehensiveOil6890@reddit
Sli

SLI has been dead for a few years, and it was game-specific support.
Dual 2080ti's would be better for AI stuff maybe due to the RAM
the_lamou@reddit
Dual 2080Tis would be significantly slower for AI than a single 3090 while using more power.
AceLamina@reddit
Yeah, it would only be better for home lab users
BaronB@reddit
The last game that supported SLI was released over 5 years ago. No modern game supports it.

No one's mentioned this but NVLink is a protocol for data center switching that strips ethernet packet heading down to maximize bandwith.
What you want is a PCIE extension which usually uses a CDFP cable and PCIE specific hardware.
You can also get higher gens in QSFP-DD but youd need two cables for 32 lanes.

I wouldn't even bother with sli, unless you are playing older games where sli did work in then maybe, but then again them games the 2080ti is probably already overkill, let alone 2.
