3870 xfire with 3870x2

post #1 of 11
Thread Starter 
I know I have heard of people trying this, but I have never heard back if it actually works. I own a HD3870x2, would it be possible to crossfire with a a regular old 3870?

This has most likely been brought up before......

yes it is possible with the 8.3 catalyst drivers that support CrossfireX, must be using Vista however.

Yup, it works. You can CF a 3870/3850 with a 3870x2.

It works just fine, and in most cases, seems to be better than 2 3870 x2's in CrossfireX.

Most programs are limited to using three gfx cards at a time. If two 3870x2's are used one just goes to waste and ends up slowing the other down.

correct in some instances the fourth GPU just slows things down.

You can also look at it this way 1 3870x2 + 1 3870 has a better cost/fps ratio than 2 3870x2.

Yup the benchies clearly show that the x2 + 3870 Xfire works just as well as the two x2's, and is more cost effective.
