Hello all, I have a xfx hd 6870 currently in my pc. I got my hands on gigabyte hd 6850 for really cheap. I have been told before that I can run crossfire with both these cards but my 6870 will be down clocked to a 6850 Is This possible to crossfire these two cards?? What would I gain by doing so?
One other question I have to ask what is the performance difference between running at 16x vs 8x
No, It should work, just the 6870 will run at 6850 speeds, so I would get a 6850. And there is little difference between x16 and x8. You could probably run at x4 with MAYBE 4fps drop, the eyes don't notice something like that.
