Can my system handle 7870 Crossfire? - Page 3

Together they were quieter, cooler and faster than the single 7970. I never had any microstutter issues and I'm not a FPS whore so as long as I could play my games on max settings with no issues, I didn't care if I "could have" had two 7970 crossfired.

I will be buying two of the next AMD card to have either 20nm/16nm, whenever that is .... But until then I'll keep my set up. I'm very happy with it.

how can a crossfired gpus runs cooler than single card????? and how could crossfire gpus runs quiter than single card???? faster maybe by how much 5% to 10%? but i bet if oc much 7970 you will like more single card than xfire card....

with better compatibilty with games than 2 cards

Hey I'm not trying to start an argument here. You guys take this stuff too seriously sometimes.

The 7970 i had was loud enough i could here it, ran at over 80 degrees under heavy load, and i get A LOT more FPS in most things with the crossfire setup. Its just a fact, i don't know what to tell you.

I cannot hear my crossfire set up and they never go over 74 degrees.

I'm not stating that my way is always better, just my experience. In fact, i was more or less just stating that the XFX DD 7970 BE, specifically, i had was loud and hot and that I've heard a lot of people saying the same.

I should imagine that both 7870s as they have more power than a 7970 don't need to run at 100%, thus cooler and quieter?

They produce less heat individually thus the coolers on them can keep them colder.
So overall they may run cooler. With good case airflow may then show an overall cooler running system.

With the right cooler a 7970 can have lower temperatures than a 7870 with a poor cooler.

usually it runs hotter, in my case the heat from the bottom card makes the top one run hotter but, i'm running 5-6 year old video cards flashed to run full tilt all the time. In his case, It can run cooler and quieter if the two GPUs are powerful enough and you have vsync turned on they... in theory they would have to work less my splitting up the work load.
