6870 CF vs 7870 power & noise??

[hiti3]

Hey there guys I have a question about upgrading my GPU. I allready own a 6870 and im considering to get another 6870 for a 100€ instead of selling this one for 100€ and getting a 7870 for 220€. What do you suggest should I get the 7870 or the 6870.

Im woried about the noise levels if I will own 2x 6870 instead of 1x 7870. Also would you know how higher would the power consumption be?

Hd 6870 x2 > hd 7870.you really need good power supply 650-700w atleast.

i'd get the 7870... lower power requirement that translate to lower heat (unless you would like to function your cpu as a heater, then get the 6870x2)

yes, but does anybody know how much noise would it generate? I have a Corsair 750W PSU so thats not a problem.

If the cards are running hot, the fans would have to spin faster ergo more noise. It depends on your case airflow and ambient temps

I've checked a few benchmarks and reviews and all of them said the noise levels for 6870 were very low, even on max load. Only a 1-3 dba more noise compared to normal 6870.

Now Im only worried about the microsluttering, its been said that the 6800 series is a great Crossfire combination to go to but I still dont know in what im getting. Can anyone explain who has 2 cards in either SLI or Crossfire

One of my friends crossfired his 6870's and long story short, you run into more problems than with a single card setup. First he had to order a longer bridge connector cause the one they give you are always too short. Then there are crossfire settings for every different game that you change in catalyst. And i would not say the 6870 is a quiet card either it can get loud. I would choose the 7870.

Aha, so does anybody else has his story? I mean I will really generate more power if I get another 6870 compared to price if I get an 7870. Any good stories

Im still looking over the internet for possible solutions, guys help! 2x 6870 or a new single AMD card for 250$?
