I was into mining for quite a while with 3 5850s in tri-fire, but I sold 2 of them because I needed money and there were just too many bugs to use it as a decent gaming machine. I bought a GTX 470 to use as my primary gaming card and I'm just trying to figure out if there's a way to throw the 5850 in with the GTX 470 and use it to mine bitcoins, or if I should just sell it too. Just to clarify I don't want to mine with the 470 because that would be counterproductive. Thanks.

Yeah you can, each of them will have to have the proper drivers and sdks installed (AMD's stream sdk, nvidia's CUDA)

i would not mine with your 470 because the 5850 are much more efficent for mining.
Keep the 470 cool for gaming so she will work longer  Smiley

I'll try it out tonight, I was getting about 340 mh/s out of each one before, hopefully I can get the same speed out of it with this config. BTW, I ran guiminer with the 470 just to see, and it only gets like 30 mh/s lol. Thanks for the help and I'll let you know how it turns out.

30? That's insane, something's wrong. I get 31 out of a 8800GT.

Even if it was 200 it still wouldn't be worth it with the 470, it uses way too much energy. I got it going last night, it works fine (282 mh/s at stock speeds) but nothing will let me overclock my 5850 so I guess I'll have to do it the old fashioned way and reflash it. At least now I can mine 24/7, I ran through 3Dmark vantage/11 last night with no problems while I was mining and there was no performance drop.

I have a 5850, it was very easy to overclock in Windows with MSI Afterburner. Now it's in a Linux machine being overclocked with atitweak.

Afterburner and overdrive wouldn't even detect the 5850 because the 470 was the primary card. I reflashed it using winflash with the core set to 885 and now I'm getting 345 mh/s so I'm pretty happy with that.
