I have a 4890 but am very interested in the multimonitor capabilities of the 5850. Can these be crossfired? I would run all of my monitors off the 5850 with the 4890 in the background for extra punch. I have heard that the 4890 is Dx11 compatible so hopefully that wouldn't be a problem.

I've searched the web on this without much success.

Any thoughts?

No, they have to be of the same series. Lucid may change this however.

No, it's only got DX10.1

No.
4800=4800
5800=5800
4800=/=5800

I'm quite tempted to just pick up a 5850 (since I use 3 monitors and I like the Eyefinity idea - cant get SoftTH to work) and sell my 4890 on eBay. Unfortunately, I have to also buy a new PSU if I want to CF 4890's.

I wonder if AMD will provide some sort of patch to allow CF 4890's to work like an Eyefinity card?

Unlikely as one is DX11 capable and the other is not, easier to EOL the DX10.1 card and move on.

Thanks monkey. Yeah, any ideas what I could hope to get for the 4890? I could throw in an old 8800 in the deal, lol.

I'm really the wrong person to ask, simply because I don't know as all my old kit gets grabbed by various nieces and nephews and I've never managed to hold onto anything long to be able to sell it. :lol:

Yes, I too am the sole provider of all computers to my extended family :) However, my current graveyard is getting expensive.
