Can a GTX 680 SLI with GTX 770?

post #1 of 7
Thread Starter 
They're essentially the same card with different BIOS. Can this be done without flashing the 780 bios to the 680?

I would say no. Nvidia has never (that I know of at least) supported SLI across cards that are not the same GPU. It might not be anything but drivers stopping you, but I'm guessing it wouldn't' work.

I cant say for certain on this particular generation of cards. But I remember a similar problem with 8800GT and 9800GT cards. They were the same card, with the 9800GT just being a rebrand. All you had to do though was bios flash the 8800GT with a 9800GT bios.

Huh I never knew about this. Well maybe it is possible, although it's a bit early to tell. Maybe wait a while to see if anyone has had any success doing it before buying the 770. Or just pick up a second 680. Performance ought to be all the same no matter which card you match your current 680 with.

i'd say just pick up another 680 becuase it will keep the cost down unless you have no limit and yeah ericeod is correct about the 8800gt being flashed to a 9800gt since i have done it before and enabled sli perfectly fine.

Except the 770 is cheaper than the 680. Kinda frags me off that in order to get my second gpu and SLI I'll have to buy an inferior AND more expensive card. Lol... That's just the way the cornbread crumbles I guess.

You can get a 680 used for around $350 easily
