Sli gpu compatibility?

[ThatOnePcGuy]

At the moment I have the 770 sc/acx 2 gb gpu and was wondering if I could maybe get a different 770 maybe from asus. What are the limitations and what other 770 is a good choice.

From what I know you need 2x same model card to use SLI (expl: 2x GTX 660 asus...) . It will not work if models are diferent (1st EVGA 2nd ASUS)....

Not true. You can most certainly SLI different brand graphics cards together (they need to be the same GPU though, for example the 770 you mentioned). An ASUS and an EVGA 770 will work together fine. Just keep in mind, if one or both of them are factory overclocked, the faster of the two will likely downclock to match the slower one. Not a big problem as you can always overclock the slower one to match the faster one.

"Can I mix and match graphics cards from different manufacturers?

Using 180 or later graphics drivers, NVIDIA graphics cards from different manufacturers can be used together in an SLI configuration. For example, a GeForce XXXGT from manufacturer ABC can be matched with a GeForce XXXGT from manufacturer XYZ. "
