Has anyone tried (or seen benchmarks) of a 4870 + 4850 in Crossfire?


I'm wondering if I should play around with another 4870, or save a few bucks and go with a 4850.
 
get another hd 4870, I cant ever give someone sugggestion on mixing cards no matter what ATI or AMD says, hd 4870 with hd 4850 would not be nearly as good as two hd 4870, you could run them both on same clock speed and overclock them pretty close to each other, if you dont overclock, you would be running hd 4870 and hd 4850, and I think in crossfire X your faster card is going to run as fast as your slowest card, so you will be running at the core clock of hd 4850 or whatever you can overclock it to.

I remember a review of crossfiring a 3850 and 3870 together, and in the review it worked pretty good. It was better than a 3850 crossfire, but not quite as good as 3870 crossfire, and better than a single 3870.

No idea how the 48xx series would work though.
 
It would be similar. The boost would be there, but not as much as HD4870 CF.
Worth checking out Rage3D's forum. Some might have a 4870+4850 setup and posted their views.

Don't bet. Considering that you could (supposedly) Crossfire a 4850 with a 3870, it's not that simple. Hybrid Crossfire, same story- onboard 2400'ish graphics Crossfire fine with a 3450.
 
I'm no longer kicking myself for getting the 3870 right before the 8800GT dropped. I'm going to try 4870x2 and a 3870. Worst case scenario, I just dump the 3870 and use only the 4870x2.
 
You cant do crossfire with 4800 and 3800, you can only use their own generation, 4800 with 4800 and 3800 with 3800.
 
I've seen multiple posts of CF'd 4800's and 3800's together. Time to search!
