    the delay was because MtGox didn't send me my password reset >.<

    oh well, will wait for the next crash, or just buy off bitpiggy next time

    Too many annoying restrictions with Bitpiggy, it's almost too hard to bother with them. You're better off with spendbitcoins, bitinnovate, bitcoinsrus or omnicoin.

    Something this volatile is a great candidate for forex trading as it seems to be on the up, could crash over night though, all we need is 1 scare and people will sell off so fast.

    i have a feeling alot well sell off when it cracks $100.

    i know a heap of people i've been talking to with some coins saying they will sell all or atleast half of there stock if it cracks $100.

    i got a friend sitting on 500 coins lol.

    The new sapphire 7870 XT mine @ 500mhs easily on a small overclock, not bad value for a gaming card of $259, pity they don't come with a games bundle.

    There almost as good as a 7950 and a bit cheaper :)

    Do a gradual sell off, don't sell it all, eg set points in stone eg you sell 50% at 95BTC, another 50% at 98BTC, another 50% at 100BTC etc so that you make sure you make all your initial money back on the first sell off.

    Then also do the reverse, if it drops to say 5-10% above your buy in price also sell off 50%, then once it goes below your sell off price consider buying in x BTC at y price.

    You then need to stick to these points and not get emotional.

    Was wondering how you had it performing in excess of 15% over the best of a pile of heavily overclocked 7870's - they are all Pitcairn and 1280 stream processors. The XT is Tahiti with 1536 stream processors/

    I'd imagine with care, those 16-17% more shaders and a slower core to start with could have you punching above the relative increase in shaders.

    Yup, there a beast of a card for mining comparatively :)

    they mine at 1200mhz on the core and do 540+

    I have them in Crossfire without much room to breath and there not external exhausts so i am runnnig the top card at 900mhz @ -20% power

    And the bottom card at 1080 at stock volts to keep the temperatures down.

    top card @ 368mhz , bottom card 484mhs

    how would i calculate wattage? i dont even think i could beat my electricity costs with my 7970.

    i have an asus 7970 3gb direct CU

    I7 2600k

    and a bunch of hard-drives, like 8. running off a 650W corsair.

    at my current electricity rate i dont even think its viable to mine for me lol.

    im giving bitminter a run for a day and im currently at 600MH/S which seems shit for my card :S

    can't figure out any of the other clients.

    Your machine is going to be quite expensive to run given the cpu and many HDD's unless you already run the machine all day (server or suchlike). Many people mined with a very low wattage sempron, 2.5" hdd (or even a usb) with 3 or sometimes even 4 58XX cards simply to maximise BTC/Watt

    Bought two 5870s to use in my old computer that has SLI for $260.

    Currently have one of my 5870s at 431Mh/s. The memory is running at 301mhz (underclock) and the core is running at 970mhz (overclock)

    Here are my cgminer arguments:
    Code:
    cgminer --auto-fan --gpu-memclock 302 --gpu-engine 970 -I 6 -v 2 -w 256

    Decided to trial run BitMiner, my GTX670 is pushing 108Mhps while my GFs machine can do 200Mhps with a very cheap HD7770...My PC is pretty useless for 24/7 use..I can leave hers going though.

    Would it be worth getting in on the butterfly labs boxes? Either of the two cheapest ones? Even if it gets harder to crunch numbers they seem to be amazing on paper compared to using GPUs. Or would I be better off just buying some bitcoins if this price lowers and sit on them?

    I wish I got into this years ago... :/

    It already runs 24/7 so it would just be the extra wattate from gpu at max

    That sounds more than reasonable on those clocks. Are you going to run the other card?

    BFL boxes are fine as long as you are either prepared to wait as they are currently more than a few months behind on shipping their first unit, or risk paying a premium to purchase a low order number unit. Personally, i'd pay a premium for an Avalon, wait for other alternatives to come to market or invest in a hosted solution.

    i've got friends and family that have agreed to let me mine on there PCs (least they can do for all the free PC building, tech support i give lol)

    what would be the best most discreet way to go about this so its not obtrusive for them? the main concern is fan noise from the GPU so it would need to be set at workload that isn't going to make the fan work at 100%.

    any suggestions?
