SLI with 2x 980 and 1 780

[raiwed]

Hey,

I was wondering if it was possible to have a triple SLi with 2 980's and 1 780?

No, you can only SLI with the same cards.

Nope. Totally different cards.

Nvidia won't even allow SLi between a 680 and a 770, which are the same chip, only clocked slightly differently. They have to be the same.

Of course, you could SLi the two 980s and use the 780 for PhysX.

no different cores wont SLI u can use that card as a dedicated Phsyx processor tho

IMO best thing u can do is sell it and use the money on a SSD or something

The thing with triple SLI is all the cards have to be identical to be evenly distributed between 3 cards. You'll notice performance issues when you attempt to SLI two different cards with the same series number. Hope this helps.

3 way sli = horrible scaling anyways and GTX980 need nothing more than air cooling

your setup will run anything at 2K maxed out with easy or 60FPS 4k with some settings turned down

People here are right that you need identical cards (with identical RAM amounts) to SLI, and that you can use the 780 for dedicated PhysX.

But you can also use your 780 as an independent display! If you use the 980s in SLI for a game on one monitor, you can maintain a separate desktop on a separate display plugged into the 780, and you'll have all of the power available from that card to drive that monitor. So, if your CPU is powerful enough with enough RAM, you can render things on the 780 while playing games on the 980s in SLI. 🙂
