Re: Mixing Graphics Cards 4650 and 5830?

You can only run 2 different cards if their in the same series, IE 5xxx or 6xxx
The problem is that every different series of card uses a different architecture, 40nm,50nm, ect and the drivers simply don't support 2 of those cards working together

Not true. My Windows 7 box is happily mining with a 4850 and a 5770.

^^^ how are you doing this?

As far as i know you just mount then and you can use them without problems, the drivers should recognize both them and they should appear in Guiminer as Devices. And yeah you probably will need dummy plugs
