5970 + 5850/5870 Questions

post #1 of 9
Thread Starter 
Hey.
How would trifire with a 5970 and a 5870/5850 work? Would I have to overclock/underclock one of the cards to get the same clock/memory speeds?

No, you can leave the clocks at thier default speeds. They will work just fine.

Alright. Will I see any significant difference between a 5850 and a 5870?

I've had a 5970 with both a 5850 and a 5870 and the benching was close with both set ups.

No big difference.

Get whichever is cheaper.

I run two 5870s and a 5970 overclocked to 5870 speeds.

I live in Norway, so no, no they're not. I'm trying to find a used one, but it's quite hard! ^^
