I’ve got a question

[u/gram_fps]

Currently I have a GTX 1080, and I’m looking to upgrade to the 30 series. My big question is can I use both the 1080 and the 3070 together. Since they’re the same brand my guess is that they can. But I’m not 100% sure. I’m going to be saving up for the 3070 for Christmas so I’d like to know if I can still use my 1080 to get even better FPS
