(quoted post by TTBit)
I set up a Kill-a-Watt to my computer and calculated with 2200 khash/s, I was using 140 watts (monitors off). According to the calculator, I should produce a block every 14 days, 2 hours, 3 minutes, or every 338.05 hours. It would cost me 47.327 Kwh to produce a block, at 12 cents per Kwh, thats $5.68 per block, a net loser.
What is interesting is the reports of the people producing 25,000 khash/sec with their video cards in the CUDA thread. If they are using less than 1000 watts (and should be), it would be profitable again to produce, electricity wise.
Difficulty level 1000 by year end.

i just did a short test on the lately released cuda-client, here’s the results
AMD X3 @2.8ghz ->stock client ~3800khs ~150Watt
GTX260 ->puddinpop’s cuda client ~33000khs ~200Watt
cpu-work isn’t profitable for me anymore, i already shut down most generators at the latest diff.step, gfx-crunching would indeed be profitable again, i don’t really wanna trust a client that fondles with my balance on it’s own though, so i don’t use it. hopefully we’ll see an open source client some day.
but your joking about that 1000, arent ya? end of the year? maybe end of the week. Grin
I don’t like the total cost of the computer. You could do without the keyboard, mouse, monitor. In addition, get the cheapest RAM stick you can find, a cheap 8GB SSD (energy saving) then install Debian 5. Access it through SSH and turn on bitcoin. You could easily do it to $300-$500 less and cut power costs by getting a high-efficiency PSU.
Someone should set up a newegg affiliate program and recommend the best bitcoin generation gear. Smiley

Once the GPU client gets perfected, I’m going to get a GTX 465, throw in a cheap dual-core CPU, 512MB RAM, and a case/cpu combo; then I am going place it in a closet and let it print Bitcoins for a year or two. Tongue It’s about a $500 investment but with patience and careful energy management it might profit.

AMD X3 @2.8ghz
->stock client ~3800khs ~150Watt Did you try -4way?
QuoteHow many hashes can I expect with a 24 core machine? I have a quad-core generating 4,300 hashes-per-second, so I am estimating a 24-core machine could mine bitcoins at 25,000 hashes-per-second. AMD Phenom (I think 4-core) CPUs are doing about 11,000khps with -4way, about 100% speedup. 24 cores should get 66,000khps. AMD is the best choice because it has the best SSE2 implementation. (or maybe because tcatm had an AMD and optimised his code for that)
There’s been so much else to do that I haven’t had time to make -4way automatic. For now you still have to do it manually. topic 820
