Last response: in CPUs
Ok ... you asked for it so here it is.
This is a sticky for discussion regarding computer hardware required for CryptoMining.
Fire away and discuss the best CPU's, GPU's, memory and associated hardware ... post your stats ... discuss what is currently out there and add anything of value from a hardware perspective ... from budget to high end.
We will review this in a week and see how it goes.
There has been a lot of discussion in the last couple of months about graphics cards ... anyone want to start there with some benchies?
I will leave this in the CPU forum area to start with.
There are two additional threads on this topic, one is in GPUs and the other is in components:
- Components: http://www.tomshardware.com/forum/id-2041828/crypto-cur...
- GPUs: http://www.tomshardware.com/forum/id-2041557/crypto-cur...
These threads deal with GPUs and the rest of the components that make up a solid rig for coin mining. - G-unit1111

I find CPU mining isn't worth it for the performance vs power used, at least in the current scrypt mining.
I have an 8320, overclocked to 4.5ghz, ram at 2133mhz and I get about 11kh/s per core when using 4-6 cores, so 44-66kh/s. When I go to 8 cores, it drops to about 8kh/s, so 8x8=64kh/s, but my PC is hard to use with all 8 cores used and no difference between 6 and 8 so at 8, something is being bottlenecked, either HT or memory or what not.
With my PC overclocked, probably drawing 150-200w for the CPU with it running at full load. That's a lot of power for a ~60kh/s rate. For comparison, a 7750 video card, less than $100, can do ~150kh/s at a power draw of 50-60w, so almost 3x the performance, 1/3-1/4 of the power, less heat and less stres of running an overclocked CPU 24/7. A cheap secondary 7750 could do way more and no impact your system in anyways if you used that card only for mining.
According to https://litecoin.info/Mining_hardware_comparison a 4770 can do 80-90 and does use less power than AMD, but again still no where what a 7750 could do and not be using all your cpu 24/7.
I don't think there is any value in x86 based scrypt mining. The thermal and electrical costs can be doubled or tripled with a cheap video card.

Good Idea REYNOD !
People get hung up on GPU kh/s rates without thinking about the big picture. Total power to kh/s rates. Sure you can pay 700 -900 hundred dollars for a 290x for close to 1,000 kh/s per card but it will take you many months to even break even when you add the power cost and the cost of the equipment.
Start small and learn, i just started with a 240 kh/s machine with parts laying around and plan to order two R7 265 if the $150.00 price holds. it should double my kh/s .
As don mentioned in his 750 ti review 4x750ti will beat a single r9 290x and be quite a bit cheaper also

Here's an interesting concept build I helped a friend put together a while ago, I ended up inheriting (no he didn't die) his motherboard, but it was a fun experiment while it lasted: Asus P7P55 Supercomputer Board, i5 lga1156 (forgot the model), FIVE gtx 290 cards. We used this for crypto hashing and pen testing for a CS class, but this thing was freakin' awesome! BTW ran off a 900w PSU
*correction it used 2 900w PSU.*
I'm pretty sure that a modern correlation of this setup could use 5 GTX750 without the need for an external power supply.

Has anyone seen a complete ROI analysis on mining? It doesn't matter what the hash generation rate is if you'll never recoup the initial hardware costs + electricity costs + added cooling costs (I guess this last one would actually be reduced heating costs during winter).

We have a x30 GPU 290 tower which has already paid itself off (circa 100 days) so everything now is pure profit. Great alternative to stocks and shares as in a year if it all hits the fan your still left with the assets and can sell the hardware for a good return too!
This heats the office so windows have been open all winter, nice and toasty! Will move it downstairs come summer. Extra fans aren't an issue as built into the Gladiator mining frame...

The IRS wants in on your virtual coin. So now you'll have computer costs, power costs and the IRS to deal with. They consider it property and since it is easy to look up the value on an exchange for how much it's worth, they expect their cut. Doesn't make much sense to me. If you're a carpenter and you buy some wood, nails and an electric saw and build a table. You wouldn't get taxed again on the reassembled good before even selling it.

Q-8: Does a taxpayer who “mines” virtual currency (for example, uses computer resources to validate bitcoin transactions and maintain the public bitcoin transaction ledger) realize gross income upon receipt of the virtual currency resulting from those activities?
A-8: Yes, when a taxpayer successfully “mines” virtual currency, the fair market value of the virtual currency as of the date of receipt is includible in gross income. See Publication 525, Taxable and Nontaxable Income, for more information on taxable income.

Cazalan how can they track virtual wallets? They can't :- D
Perhaps you haven't heard of the NSA? I'm not saying they will, but unless you can afford a good lawyer it's generally not advised to cross the IRS. They can ruin your life. The gov is 18 trillion in debt. That's $60,000 per US resident, but closer to $180,000 per tax payer. If they get your name from an exchange and realize you're not putting anything down on your taxes they can flag you for an audit.

Cazalan, the number of people mining is a spec of dust in space VS the masses earning money through official means/paid jobs etc. I think your overestimating how many people do this, and more importantly how many people do this and actually make a profit ;- )
Well I did get a bill once from the IRS for 60,000 so I'm a bit more paranoid about it. That took a couple months to clear up and it was an error on their part. They were going to seize $3,500 of my salary a month from my employer until the balance was paid.
Anyhow it's not about profit because it's not treated as a currency. It's treated as property. So the minute you generate a bitcoin they want their cut. So just generating 1 bitcoin would raise your income by $1000 before the crash. Which depending on your tax bracket could mean an extra $200 to the IRS.
It probably would take a few years for the IRS to start catching up with this stuff but they will eventually. There was a time when they weren't even monitoring stock options trading.
Anyhow a bit off topic, but figured people wanting to get serious about mining might want to know what they're in for.

There are really three types of miners.
1- hobbyist, doing it for fun and knowledge. same as folding, boinc
2-enthusiast , i have the good hardware for gaming might as well let it pay for itself.
3- Farmer, how much profit can i get from a acre(k/hs) multi rigs or dyi farm
The IRS will most likely not be concerned with 1 or 2. But three will get a high level of scrutiny. Including the meter company when they see the increase in electricity use.

Whatever you do, don't go this route:
http://arstechnica.com/tech-policy/2014/02/harvard-supe...
The worst part is the supercomputer cluster is 99% CPU power. 17 hours later (and about $1000 in power usage) and he successfully mined about $200 worth of "Dodgecoin"
Much coin
Very power!

All those miners buying up amd cards are driving prices crazy high. Why does mining use a GPU and not a CPU? GPU can do 10x the processing a CPU can for this type of task. For example, my 8 core CPU would get about 11 kh/s, 8 cores, 88kh/s. My 7870 GPU, nothing that great in terms of top cards, could get 350 kh/s. 4x the rate for a GPU that costs the same as the CPU. Now add 4 videos card, 1 CPU on a motherboard does 88, 4 video cards does 1400.
And ASCI mining, a way using small CPU's made just for this task, are taking place and the GPU mining is dying, there is no more inflated cards. In fact, prices are dropping. Used cards are cheap as hell as miners are dumping their cards, and manufacturing, take a year to get card production up enough to keep up with mining demand, now will have tonnes of excess cards and will dump them. Retailers who couldn't keep them in stock, started ordering more and more, and now are stuck with lots of extra cards, and are selling them on sale. AMD prices are going down, not up. That was so last month. lol.

Is it even profitable? Do you need to know code to get into it? Because I don't really care about learning code.

The best part is you need ZERO programming knowledge to get started, however basic math skills and a robust knowledge of computer hardware will get you much farther.
You don't need to do any programming, and can download pre-made miners which will simply let your computer do all the work for you.
BE WARNED! The biggest factor is electricity/hardware price compared to profitability. You need to spend a lot of money on a dedicated GPU miner or ASIC unit to see a return on your investment before the hash difficulty makes this a loosing investment. Alternatively, running a miner on old hardware may also be a losing game as the $electricity/$mining ratio approaches and surpasses a 1:1 ratio. If you want to see a return on your investment, get GREAT equipment and run it as fast/soon as possible as you will soon see a diminishing return on your investment as the hashing difficulty increases.
So don't try this on a CPU, outdated or energy inefficient hardware, and do your research before buying into it, just like any other investment.

For those who hopped on the bandwagon early, a 280 or 290x could have earned you $300 a month at the beginning of the year.
Given all of the companies developing their own ASIC farms (I saw one which consisted of 4 million clustered ASIC boards), this is one trend which was started grass-roots and supported by the community, but now is being taken over by those who can afford the investment (the super wealthy).

Here lies the end user profitability of PC hardware for Crypto mining... May it rest in a million distributed and highly encrypted pieces...
As stated above, CPU mining won't recover your power bills. The same is true for GPU mining. On the plus side, AMD has posted a $500 discount on their flagship GPUs. I suppose the supply overshot the demand by a large margin, since no one is using these to mine anymore.
