I believe you NEED to have the same models to have it to work

Nope there are rumours out there that you can actually crossfire the 3800s with 4800s! I am sure its possible.

I'm getting an extra 3850 to crossfire with my 4850. All reports say you can go between series.

If it can x-fire between those two, Then it will both run at 3870, it's all I can tell

Wrong. It balances the load.

Lets say the 4850 is twice as fast as the 3850. The 4850 will render two frames, then the 3850 will render one, and so on.
In Progress...

Yeah, it will work, but I wouldn't expect HUGE performance gains.

Think again, CrossfireX shows spectacular gains across the board. As long as the card your adding in (as slave so to say) has enough compared power to make a difference. (Which the 3870 is a powerful card, expect 15fps gains i predict.)

But he's adding a 3850.
