Hi,
It's my first topic in here, so don't yell at me if i post it in wrong place:)
I am going to buy new computer for pc games, but i am also going to use it as rig. It's going to be 2x 5870 GPU's. The question is - if i have windows 7 professional 32bit (can change it to 64 if needed) i will be able to run miners on both gpus? or i will have to change anything/install software or something? Also i heard about turning out crossfire. How does it affect mining / games? or it's impossible to mine on crossfire? A nice explanation on topic will be nice as i've seen on wiki that there are 5870 x 2 statistics.
Best regards, Jakub

The grue lurks in the darkest places of the earth. Its favorite diet is adventurers, but its insatiable appetite is tempered by its fear of light. No grue has ever been seen by the light of day, and few have survived its fearsome jaws to tell the tale.

I am running a Win7pro 64bit with two 5870s.
I had no probs running miners on both gpus. You have to have two miners running. Change the Device to =1 and =2 for each miner bat file.
I did not crossfire them. It does not matter for the 5870s. You can have them crossfired, or not. Same performance either way.
Make sure you upgrade your PSU. I would recommend a 900Watt or higher PSU.

Using poclbm and was getting 358 on my first card, and 370s on the second. I could push them more, but they would crash. You need to just work it up to a level that is borderline crazy.

You don't need a 900W PSU. You need a high-quality PSU such as Seasonic X-series, 750W tops but 650W should do fine too. Anything which is not from a known brand is utter junk, and even within a brand some products are good and others not so much.

It's amazing to me how awful the PSU market has become. I had good luck with Antecs for several years, but I have one here (SP-450) that crapped out, because apparently it had defective capacitors. "Japanese capacitors" is now a feature that is used as a selling point. Wattage ratings are completely useless. Oh well, I'll try my luck with Corsair.

I still stand by my recommendation. A bigger PSU will have better effiencies.

Once you do that increasing the power rating will have almost no effect.
