980 sli with 770

[sMiLEy sLOth]

Hi awesome people,

Just wanted to know if it's possible to run a gtx 980 in sli with a gtx 770? Amd if it is possible, is it even worth it?

Also, in the future I will be running 2 980's and wanted to know if a 750w psu will be powerful enough to run this? The processor is an i7 4820k. I know it's not a lot on info but it's for a customer who has only given these details and asked if I can do do the job.

Thanks for any help in advance,

no

Nope, But you can run the 770 as a dedicated PhysX processor though.

Not in SLI no, you'll need 2 of the same card to do that. But you can use the 980 on a Primary monitor, and the 770 for a secondary monitor.

 

Or you could use the 770 purely for PhysX or something (I think, correct me if I'm wrong )

Thanks all. I thought that was the case but I wanted to make sure.

Unfortunately no you can't do that.

AMD allows GPUs of the same architecture to be thrown in Crossfire.

SLI is picky, It has to be the same GPU and the same amount of Vram for it to work.

You would have about 250 watts left, You could have 3 of them and still have about 125 watts left
