I sold 126 coins at $3.10, about 1.5 weeks ago, real ticked now that they went up to $4.60 a pop
If coins drop below $4, then yes that would be the case. If that does happen, I plan on buying up a ton.
better hang on to your cypress and caymans, tahiti is roughly on par with 6970 in bitcoin hashing.

Why did you sell at <$4 when your plan was to buy up a ton of them if they ever got that cheap?
Bitcoin mining likes as many alus/cores as possible. The 7970 has 2048 which isn't a huge upgrade from the 6970's 1536 alus or the 5870's 1600 alus.
It's not really how many cores you have, it's the microarchitecture that most dictates what your performance is going to be. VLIW5 was very good at hashing, but was not a good general-performance GPGPU architecture. GCN, on the other hand, was designed from the ground up to be a more generalized architechure. Which reduces performance in certain tasks, (like hashing) but increases performance dramatically in just about everything else.
Define tiny. My cost is about $1.90 per coin, so I'm happy that it regularly spikes to ~$3.00 or so.i'm sitting on ~300 coins, still mining at 4000mhash/s right now. i'm just purely gambling that there will be an uptick once again. I plan to ride it out till spring and it gets warm again. if the difficulty can stay where it is i'm making a tiny profit a $4/coin, but if by chance we a spike to 10,15,etc. i'll be a campy happer.
I calculated that it costs less than a dollar for me to mine a bitcoin. 4x your cost is a pretty good profit. Any idea how this would affect video card life if the GPU runs at 55C? That is pretty cool for a video card.
Why on earth would you do that? $500+ for the same BTC performance as a $350 6970 (or worse, $250 unlocked 6950 or less than that for a 5870).Who's getting a 7970 for mining? :biggrin:
The world is full of weird people? ;-pWhy on earth would you do that? $500+ for the same BTC performance as a $350 6970 (or worse, $250 unlocked 6950 or less than that for a 5870).
You just break even?Thought of putting my 5870 to work to buy a 7970, but after seeing BC results I changed my mind. Probably will still do some Mining and spending on something else though.
You just break even?
Sorry, I meant your bitcoin careerThe 7970 is slightly better, 20-30% IIRC, not enough to spend $5xx on IMO. If it was 60%+ I'd be more tempted.
