I don't quite understand what you're asking.....

I think he is asking what better one 3870 @16 speed or two 3850 in crossfire each running @ 8 speed for a tatol of 16 speed. But I could be wrong.

The slot speed makes no difference in my experience.

Go with the crossfire 3850's but make sure they are 512mb versions or you will be bottlenecked in newer games by lack of vram.

I believe that 2x3850 512's is greater than 1 3870, but the cost is definitely greater.

what monitor are you using? because crossfire 3850s would be better at higher resolutions but at lower resolutions i would go for a single 3870
post #10 of 10
Orrrrr.... get one of each

CrossfireX is due out in March, and 1 3870 and 1 3850 in CrossfireX would be better.
