Hi guys, im still running a 5850 and 5870 mining rig - 0.04 PPS (so far mined 12 BTC off the whole system)
i ahve a 6850 sitting doing nothing atm, is it worth the hassle of buy 3 PCIe risers and customising my case to suspend the GFX cards for the extra 200-220 Mhashes?
i was running the card in a separate PC for mining LTC but now my office gets way to hot running two mining rigs, im guessing that a third card wouldnt really help with the heat anyway - its not hot in my case - both cards are around 65-75 degrees all day.
What's the rating of your PSU? You will need something approaching 800W. I alway use a 1250W PSU for 3 card GPU rigs. Power problems cause all sorts of crap which will waste your time!
