Hello,

I have an XFX 5770 and the opportunity of getting a Sapphire 5770 at no charge....

Is it possible to crossfire 2 5770's from different manufacturers?

Thank you.

ASUS P6X58D / i7 930 / 6GB Corsair RAM (3x2GB) / win 64 ... if this makes a difference

Absolutly. They are the same GPU. However, if one is a 1GB card and the other a 512MB, it will match the memory size to the smaller one. So a 1GB will only use 512MB or the available it has. Just for reference, any ATI cards in the same series can be crossfired. A 5770 can CF with a 5770 or 5750.

All you need to do is plug both cards into their PCI-e slots, and then use the crossfire bridge to connect together. After that you go into CCC and enable Crossfire.

So-long as your graphics cards have the same speeds they will work fine, If one is overclocked however it's speed will be reduced to match the lesser card in the configuration.

All you should need to do is install and put in the correct power plugs, put the Xfire bridge on and then make sure all your settings are correct in CCC and then viola you should be finished.
