Thats too bad you have quite a good collection of cards. If I had the money I'd invest in the reference 5870's but I just built a rig with 5 5850's.

Always trust your self over some one else. Having other people hold your money is like giving your money to the bank. These banks attract attention from hackers and are more likely to get robbed. The difference between real banks and your eWallet sites is the fact that real banks are federally insured.

Stick your wallet on a thumb drive or two for simple security.

You'd obviously need extenders and it cant really be used for anything other then mining but yes it would work fine.

Too rich for my blood. I'm out

It isn't overkill... 4 5830's overclocked to 1030/350 draws around 900 watts

101.01€

costs 60 dollars I run it and it keeps them super cool.

Considering these are used it depreciates the value quite a bit. The only part in the case that you could ask retail for are the 5830's which are no where.

Used parts depreciate at least 10% but most likely 30%. Ill be nice and say 10%.

We'll keep the 5830's at 130 because that's a fair price for them used.

The rest of the stuff could cost around 700 new. 10% off that would be 630.

That makes the total 1,280 with out tech support.

Lets be honest putting systems together for anyone who knows how to use google is very simple and most likely you'll have to take it apart for the shipping process anyway so that shouldn't even be considered a feature. Next your not bestbuy you cant charge 600 dollars for tech support. To give you an example with dell you can get a 4 year 400 dollar warranty that allows for tech support, free replacement parts AND they will put it in your computer for you.

Will you honestly replace broken parts within the month? I doubt it.

For the kind of "tech support" your giving at most you could charge with out robbing some one is 50 dollars and even that is quite a lot.

My point being that you cant justify a 600 dollar mark up off retail prices when your selling used.

I decided to calculate the cost of the 5830 brand new. I had to guess on the case cost and mobo but I feel I was more then generous in those situations.

5*130-5830
12*5-extenders
280-psu
10-flash
150-mobo
10-ram
40-cpu
100-case
15*3-fan

total=1,345

Your asking for 2 grand for something that could cost 1,345 brand new. You also cant argue that you cant find 5830's anywhere because 6870's are the same card for 20 dollars more so at most it would cost 1,445.

Your asking around 600 more for a used computer. Like I said way over priced.

If you are going to use afterburner make sure you did this. https://bitcointalk.org/index.php?topic=18102.0

I'd also like to note that I had stability issues with my sapphire 5850's when I changed speeds in afterburner. If you seem to have the same problem try using trixx because I have had no problems with that.

Seems extremely overpriced. What are the exact specs?

Look up the guy I recommended he undervolts and overclock the core so you might get low enough temps.

I HIGHLY recommend contacting the user teukon. He has the best megahash per watt out there for the 5850. He said it in some thread in the hardware section but I'm way too lazy to find it.

I assumed that the price he hopes for.


You might be right I assumed at those speeds it was a 5830 but he said "another 5850". With a single 5850 you can definitely achieve 400+. When you have 5 5850's with an inch gap between them you should expect around 385.

I gave a 2 month window. So while I agree its not very likely to get to 30 dollars a btc again its entirely possible.At the very least you can expect the price to go back up. If bitcoins is going to be successful in the long run we will need to be able to buy a bigger variety of items then currently. If that happens it will drive the price up because people will start using it for things other then speculation. I was just pointing out its not really wise to sell right now if you think bitcoins will succeed the price will go up.

Most likely you already use 2 kwh/day before accounting for the rig so you should calculate at the 13.32p rate. That means it costs you 64p

290 actualy should generate 0.154 btc a day so thats 28.4p a day

In all honesty though you really need a rig that has 4+ cards in it. For example my best rig which is 5 5850's requires about 1000 watts and generates about 1.925 ghash. That's 1.025 btc a day. Using your rate for electricity it costs 3.20 pounds a day. Making 1.025 btc a day and subtracting the electricity would be 2.95 pounds per day.

Keep in mind though the price may go up in the future and any btc you don't sell now could be worth alot later on. Lets say you didnt spend any btc and just paid your bill for a 2 months and then it jumps to 18 pounds a btc. That means the 9.24 btc(I realize this isn't exactly accurate) you saved up is worth 166.32 pounds. The cost in electricity for the 2 months would be 17 pounds.

That means you made 149.32 pounds so its all about when your willing to sell your bitcoins.

Pretty sure your in new territory. I don't think many people have messed with the 68xx series cards.

I have a meter and a healthy over clock for the 5830 requires about 190 watts each so you definitely shouldn't put that on a 750 watt. If your running stock core clock and lower the mem speed you can get away with this but otherwise you cant.

Which is 129 usd and around what I said the lowest any one should sell for. 129 usd is 13 btc not 10.

That's an extremely low ball offer. I agree you can get one of these new for 185 or 130 euros but your asking for over half off. If these were mine the lowest I'd sell them for is 135 usd and that's if I was extremely desperate.

I was pretty accurate with my estimate then for the 5830 rig if you paid 130 per 5830 (I guessed 559+520=1,079). Considering your selling used you shouldn't be marking up the price 250 dollars. You can find every part in your comp right now or an equivalent alternative for the 1050 price brand new. As for setting up the os ect any one who is buying a caseless rig should be well aware how to do this with ease.
