Hi everyone,
I believe that I saw a similar thread somewhere but I couldn't find it anywhere.

I have two Evga GTX 780 (3 way sli) already in my workstation, They are amazing and all, but my motherborad (P9X79 WS) still has two empty pci-e slots, and I like to fill them with another couple of 780, or one (maybe two) 790, if god said "There shall be 790 GTX".
Since the GTX 790 is shining in the horizon, I decided to buy one, and plug it with the two 780.
Now, I don't know if that is possible or not, but if it is, I'm not sure how is that could be done. I may need a special connector or something .. right?

I'm afraid if I connect them the usual way, it may drop the power of GTX 790 to the half, or maybe it won't work at all. I'm talking theoretically off course.

The GTX 790 doesn't exist?

Even if it comes out you cannot SLI it with a 780.

I know it's not out yet, and it may not exist in the near future, so, I should buy 780 instead of waiting for 790 ..

But the cards I have are 3 way sli, will that work with 4 cards of 780?

Won't work with a supposed 790.

You can 3-way SLI 780's but the scaling is reportedly horrible compared to 2 x 780's, so really it seems like it would just be a waste of money.

Thank you.


Sorry to pick up on a dead thread, but did you consider selling your two EVGA cards and buying two GTX 790`s and sticking them in SLi when the time comes?

Or were you daydreaming?
