Crossfire newbie

[Momo]

So i've got an XFX 5850 reference. My brother has an XFX 5870 reference. He's gonna give me the 5870...

could i crossfire these things? The 5870 would run as a 5850, right?

Thanks, and please don't flame too hard on the newbie question

Here is a nice write up from Legit Reviews going over how mixing the two cards will work in crossfire. Looks like a nice free upgrade for you as long as your motherboard supports it.
