OK you asked for it - there there are already two similar discussions going on regarding crypto currencies:
- The first is in the CPUs forum started by moderator Reynod: http://www.tomshardware.com/forum/id-2041369/cryptomini...
- The second is on what makes up the rest of a rig suitable for coin mining: http://www.tomshardware.com/forum/id-2041828/crypto-cur...
This thread will focus on discussion with crypto currency mining and graphics cards.
This is a moderator sanctioned thread for discussing the best graphics cards and graphics hardware for mining the hottest crypto currencies. There has been a lot of discussion with crypto currencies and graphics cards, particularly of the AMD 78XX and Radeon R9-2XX series (and interest in currency mining has heavily driven up the price of these cards). The Radeon 79XX are also particularly adept at crypto currencies such as Bitcoin and Litecoin and as such the prices on those particular cards have skyrocketed due to the high demand.
We will be monitoring this in a week to see how this goes. Remember - keep it on topic and keep it civil! All off topic posts will be deleted and this thread will be monitored by myself and the other moderators to make sure that this will remain on discussion with crypto currencies and currency mining.

how about x11 and x13?
Depending on which coin you mine, you can probably make <$1.00 to $1.50 per day if you use those 3x GTX 750ti's. Let's take the most profitable X11 coin on this page that a google search threw up: (link), "SaffronCoin-X11 (SFR)". Using the profitability calculator it links to (link) and assuming that each of your 750ti's mine at a rate of approx. 2.5 MH/s for a total of 7,500 KH/s, you can expect to make around ฿0.00231704 per day which is equal to $1.47. If you are paying for power and you assume that each 750ti uses 60 watts max plus your CPU at ~35 watts and the fact that your 80 plus rated TT Litepower PSU is losing around 20% at the wall socket, you are using about 250 watts or .25 kw/h. If you are paying 20 cents (USD) per kw/h, that is $1.20 per day. Even at 5 cents per kw/h, you are spending 30 cents per day or nearly 20% of your total income. Now, lets assume you paid retail for each 750ti or around $140 plus shipping and tax; so $150. Actually, lets assume you got them on sale for $120 each with free shipping and no tax from Newegg (link). So, you paid $360 on just the GPUs. It will take you 314 days of 24/7 mining before you pay off just the GPUs (assuming your power cost is 5 cents per kw/h). Add another $150 or so for a motherboard with at least 3x PCIe slots (or you can use risers on a cheap board which will still cost around $20 each + price of board), the price of a 500w PSU, the price of a CPU and price of RAM and breaking even will take even longer. Unless you can find a coin where you are making at least $10 or more per day after power costs, or if you already have the hardware and power is free or very cheap, invest your money and time in something else. Unless of course, like I said before, this is a purely educational project.
thanks!. well i think i'll mine what i can with my 260x. i just cant resist to mine new coins. just having 10-20 coins per cryptocurrency will be fine hehe ill just hope my coins will be priced high on the future just like bitcoins

i have a thermaltake litepower 500w. for the mean time, will it be enough for 3 750ti and mine maybe 16-20 hours a day then ill upgrade to a 650w when i get another cardPlease tell me you are joking and that you didn't just buy 3x 750ti's for mining. You are literally not going to make any money. Also, the best bang for your buck in scrypt is the gridseed, unless they came out with an even more efficient scrypt ASIC. The gridseed is $55 to $60 shipped and gets you 300 kh/s out of the box stock. It uses less power than a thumb drive (2.5 watts) and many people have reported that it can be overclocked to around 400 kh/s. By comparison, each 750ti is going to draw around 175 watts and you are barely getting 275 kh/s per card. Oh, and they cost about $150 each vs $55 each for a gridseed (link to a gridseed for $55 shipped). You are going to discover that you are paying more for power than you are actually making (which is going to be about 10 cents USD per day). Unless you plan on buying like 100x GTX 650ti's or 100x gridseeds, the entire concept is a waste - unless you are doing it purely for educational purposes? I was mining scrypt up until around March with my 7950 which gets 650 kh/s and I also had a 270X which was doing 420 kh/s, so a little over 1 Mh/s. By Sept. of last year, I was making roughly $15 per day and power cost me around 15 cents per day. By March, I was making less than a buck per day. I still have my 7950 and if I were to fire it up for mining again, I would barely make 10 cents mining even the most profitable alt-coin. That is a net loss of -5 cents per day. Unless you are getting your power 100% free and your GPUs, PSU and rest of your rig are 100% free, you won't make any money. Even if your power is 100% free, you won't break even on the price of your GPUs for several years. If your power isn't free, you also have to take into consideration your CPU. Even at idle, many CPUs consume 40 to 50 watts of power. You will also have to add at least 25% on top of your total power consumption because you are losing about that much in heat due to your garbage non-80 plus Thermaltake Llitepower power supply.
thanks for the advice. in another forum someone told us that he has 6x 750ti. mined an altcoin for one month 24/7 then traded it to bitcoin and earned him 2.5bitcoins. i dont know what coin he mined though. also i think 750ti only consumes 60w. every review is saying it is 60w
That is right, I was looking at the 650ti. It is actually more like 70 watts since you are going to be at nearly 100% load. Most of the reviews are measuring the load when either gaming or running a benchmark test which usually never hits 100% load. But still, that 60-70 watts is about 30 times more than what a gridseed uses. Mining with a GPU is just not smart anymore no matter what card you use or what coin you mine - scrypt or sha. You are about a year or so late to the party.
how about x11 and x13?

can you give me a website which ships gridseed internationally? you cant find one here in the philippines. thanks
got a reply from the other guy. he said he mines with a 6 750ti x11 algo. then trades it to btcoin. dont know what x11 algo coin he mines
