Need help with connecting GTX 980 and GTX 680 in SLI

[intxcotton]

I have just purchased a bigger case, so i can fit my new gtx 980 which i am trying to sli together with gtx 680. Can you please give me some tips on how many sli bridges and power i need, i have 750W PSU.

You cant. Nvidia can only SLI 2 of the same GPU's

although you cant sli a 980 and 680 together you can still have them both in your system running the primary gaming monitor off the 980 and 2-3 monitors on the 680. This will give you the best performance for gaming on a single monitor while being able to offload the physx and 2-3 monitors to the 680.

Also a gtx 680 can only support up to 4 monitors.

So he is wrong?

you could use the gtx 680 as a physx card... but i wouldn't recommend it you will see very little gains and up your power use / heat to much... Best option is to just sell the GTX 680.

No he isn't wrong... He is not talking about SLI'ing at all... and what he is suggesting will only give maybe 1-2% better performance in games, its pretty much a complete waste of power, and it generates more heat. Just sell the GTX 680.
