Can I run a stable dual monitor setup with a Sapphire Radeon 7770 OC Edition and a Sapphire Radeon 5770?

Motherboeard: ASUS P7P55D-E PRO
PSU: AXP PowerSupply 630W

The thing I am planning to do is running dual monitors, one for gaming, and one for running desktop whilst gaming, but my 7770 doesn´t have two outputs for monitors, it only got one... My 5770 does on the other hand got two, so if I can run crossfire with them, can I still connect two monitors for my different GPU´s and still be able to run fullscreen (lets say League of Legend) while I am watching my stream on the other, without any problems of my coursor running away to my other monitor, and is there any way to easily change where my coursor is?

No you can't. They have to be from the same generation.

no you can't. amd doesn't allow it for various reasons. for one, the cards have very different gpus and architectures. second, amd provides no driver support for crossfiring 5770 and 7770.

You can do what you are wanting, but realize its not crossfire. Crossfire is running 2 or more cards in conjunction so all of the power goes to one card. This limits you to using the output on one video card, and like the previous posts have stated you cant crossfire cards from seperate generations (except the newer R series with some of the previous 7 series since they are rebrands of the same card). However you dont want crossfire, you simply want to hook up more monitors. You can easily run each card independently and use the outputs on both. Just dont put a crossfire bridge between the two cards.

When running games, run them in full screen and they will automatically take over whatever screen is primary and the mouse will lock to that screen when running full screen DX games. If you want to move the mouse to the other screen to do something you have to alt+tab out of the game (or hit the windows key).
