Crossfiring a 4850 with a 4870?

I was told recently that it is possible to crossfire an ATI 4850 with a 4870. Has anyone else heard this? The reason I ask is because I may be getting a 4870 and I already have a 4850.

Yes it is possible, that is the + side of crossfire you do not need the same gfx card and brand. Although you will not get a massive improvement in proformance such as 4870x2. It is a good idea, just make sure you have a PSU with enough W's and you should be fine.

Looking at your PSU I think 650W will be fine as the recommended for 4870x2 is 700W. Here is a picture I found on http://www.hardwarecanucks.com/foru...0-hd4850-crossfire-performance-review-15.html
