Cryptocoin Mining?

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.

better hang on to your cypress and caymans, tahiti is roughly on par with 6970 in bitcoin hashing.

While I wouldn't my breath, it could get better. 5 and 6 series performance wasn't as good as it is now originally, it took several improvements and additions to the mining software to get where we are. There may be some missing optimization in play here.

That said, you would be insane to go and buy a 7970 just to mine bitcoins.
 
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.

I was talking about strictly bitcoin mining performance. Of course GCN is better at most GPGPU applications as that was one of its main focuses. No doubt that GCN is going to be better at more tasks than VLIW5 and VLIW4.

Define tiny. My cost is about $1.90 per coin, so I'm happy that it regularly spikes to ~$3.00 or so.
 
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.

55C is really nothing, most of my mining rigs were running at 80C+ 24/7 for several weeks without issue back when the BTC were worth more. That said, maybe I've taken years of life from my 5830s in that time span, but I'm pretty sure 55C would be as safe as houses.

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).

The world is full of weird people? ;-p

I am set on gaming, mostly. No way in hell, I am paying this $ for it. There are ways to get it cheaper, though.

2) I haven't owned a top card since 7900GT days.

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.
