Would this work?

[Sir Shfvingle]

I already have this card http://www.newegg.com/Product/Produc...82E16814102883
Not that I'm gonna do it, just thinking, If I wanted to crossfire it, and since that model is out of stock, would it be compatible with this card?

Same type and company, just 2 Gb.

Yes, but you won't have the ability to use the 2GB on the Eyefinity edition (would be limited to 1GB).

As that's the case, you'd be better off buying a cheaper model, like this.

[Sir Shfvingle]

I see. What is the reason for that?

[mrcrusty]

Multi-GPU configurations forces the cards to share bandwidth.

So if you have two cards with a different memory size, CrossFire will utilise the highest amount of memory that is available to both cards. In this case, 1GB.

You are better with a 5850 in Xfire really.
