Just want to know...

[nokturrduk84]

I'm not buying it, I just want to know, if there is possibility to have 2x 7990s in computer and working them in crossfire? I ask cause, it's dual gpu.

[Loe]

Yes

[Coombzy]

yes it would be quadfire it works but the scaling is bad on 4 gpu configs.

[Hans Christian | Teri]

Yes, but the scaling would be as terrible as when you run 4 single GPU cards together. Long story short it's a bad idea.

[Bluejay0]

Quadfire. But it's really not recommended.

[Bluethulhu]

It's certainly possible, though certainly not practical.

2 7990's would make sense if you were going to buy 4 7970's, id rather less cards in the system. Im not exactly sure if 7990 is identical in performance to two 7970s though

Not exactly. In comparison with the 680 v 690 situation, It's better to have separate cards since the scaling is actually improved.

ahh okay, yeh i haven't really researched that stuff properly because 4 gpu's is that pointless. oh and btw i thought the 690 was dual 670's?

Never, the x90 series is always been two of the flagship model GPUs Ex. 680 580

oooooh well you learn something new every day

Yup. Like never buy the lowest end card of anything EVER

Maybe noob question, but what is scaling?
