Hi,

I ended up with a 5830 a few weeks ago due to a problem with a friends PC not accepting this card. In my machine it works fine however, so i gave him my old 4870. Wasnt what i wanted, but he ordered that card, but it was a bit of an upgrade for me.

Anyway, i'm grabbing a new 24" LED monitor soon (using 22" at the moment) and thought about adding a 5850, considering they are cheaper that they were.

Can it be done without dropping the speeds of the 5850? Many people suggest it is possible with the 58xx series, but the older 4xxx series and nvidia SLI cannot do this. How much truth there is, i dont know!

Would i be better just adding another 5830 @ £145? Or should i try and sell the 5830 to fund a single 5850?

Thanks. :)
 
Ive never done it, but I'm sure you could. I would think the 5850 will slow to 5830 speeds, well it would have to one way or another.
 
It will work, the 5850 will not drop to 5830 speeds (if I remember correctly), but I'd say get a 5830 since you already have one. At that res (assuming the 24" is 1920x1080) the xfire 5830s will perform really well.

It might work out quite well. You would have 5850 speeds in all the non multi GPU supporting games and crossfire 5830 speeds for the rest.
 
The more I think about this the more it make sense.

If you had say a HD4890 you add a 4870 and have 4870x2 speeds in crossfire games and 4890 speeds in the others !

Win win ?
