Hello,
i have 5850 ruuning in crossfire would adding a 5970 be compatible with this setup?

You cannot crossfire with a card from a different series, you can crossfire any 58xx card with another 58xx card.

HD5850 CF is powerful performer. So you should have nothing to worry about there. :)

woah, you should be able to crossfire 2 x 850 with a 5970 for quad fire as the 5970 is 2 x 5870 which can be crossfired with 5850's

though i agree, 2 x 5850 should be powerful enough for almost anything

^^Ok, so we can run two HD5850 and HD5970 in the same PC?

What's the rest of your rig and the purpose of it? Adding a 5970 might (most likely) be overkill. You're running near 5970 speeds already except what a 5970 is 2x 5870 GPU's downclocked to 5850 speeds and thrown on a single card.

In addition to that, the CFX scaling is slightly better on a 5970 than actual CFX between two cards.

If you are willing to drop the money on one, I would sell your two current cards and buy a 5970, odds are that will be more than enough. Plus assuming your mobo has room for a second 5970 you can have 4-way CFX at a later date which would just be complete and total overkill for just about anything.

my rig

i7 930 clocked to 3.8ghz -yep im a oc noob

x3 1tb Western Digital 7200rpm 32MB Cache
asus rampage 2 extreme
Corsair Professional Series Gold AX1200 Modular PSU -on order released end of september using a thermaltake 650w till it arrives

CoolIT ECO cpu cooler
windows 7 home premium 64bit
x2 5850
razer naga mouse
g15 keyboard

mainly use the rig for gaming bad company 2 rocks were just interested if a 5970 added would make a difference/possible to do but after reading more info guess adding it to my crossfire setup would be a waste of money as there probably wouldnt be a great increase in performance that justifys the cost thanks for all the replys

yeah, anything past 2 graphics cards usually don't scale all that well

Just for the record I have the XFX 5970 Black Edition and it will play ANYTHING currently maxed out. 1680x1050 Extreme everything, 4xaa Warhead 58fps. Even Metro 2033 DX11 maxed out smooth as silk.

Yeah what a total waste of money that'd be for virtually no gain. Crossfire scaling is already iffy the higher you go. It's been proving time and time again, the sweet spot for Xfire and SLI is always 2 cards.

Yeah it's a beast, I had a sapphire 5970 but I had to RMA it (Will be getting my replacement today!), so I have not been able to see the real performance on my rig yet. Hopefully they did not send me yet another defective card.
