is my choice

wrong place, should be in marketplace ...

Which happens as wire transfer behind the curtain OR is a very expensive merchant account for CC processing.
Just goes to show how little you know.

First of all, you should learn a little bit of english, if you want anyone to understand you.

Wire transfers are FREE here. I'm talking about PP and CC payments, you said CC is far superior. No one was talking about wire transfers.

Currently users have no need for BTC because so few places accept BTC. We accept on manual request, but only manual as long as there isn't a WHMCS module i'm confident enough with. At this point we have to charge a little bit extra for BTC payment due to it's volatility.

You clearly have absolutely no idea what you are talking about. Were are right now in a state where there is NO demand for BTC payments from merchant point of view, because users see no supply.
As soon as there is a little bit more supply, users will adopt when they see the all around benefits. Stabilizing exchange rate will help there as well.

It's true however that the sole reason we accept PP is because by nature 97% of webhosting payments are via PP.
However, if it would be convenient for us we would push more for Alert Pay, and probably Liberty Reserve too, along with WebMoney and some Asian gateways, unfortunately, becoming a merchant with them has been made rather .... Annoying .... To say it very mildly.

If we would present all those choices, i would bet usage of PP would drop to around 40%-50%, mainly being US and UK customers. But at that point we would also add an extra fee for using PP, allowed by accepting Western Union with even heftier fee At that point PP usage would plummet.
However, right now convenience trumps other benefits, managing a bunch of different payment methods can create a lot of extra burden on managing cash flow.

Did you know that PP TOS denies you right to charge extra fee for using PP *unless* you accept some other payment method as well with the same or higher fee?

PP is currently killing their supply side (merchants), so it's only matter of time supply for BTC services becomes great enough for mass adoption buy consumers (demand of BTC paid services).

So wake up, and get first some experience and knowledge about things you don't clearly understand the slightest bit.

WOW! You really don't know what you are talking about.
CC might be cheap for the consumer, but not the merchant!
I operate a small business and pay so much in PP fees it would hire 1 guy fulltime! This with significantly lower than CC processing fees. Changing to direct CC processing now would double up the cost probably.

Right now Bitcoin mostly matters for online purchases, anyone looking to make online purchases does not need any additional investment to utilize Bitcoin. NADA.
Only investment is a little bit of time to install bitcoin client, register on Mt.Gox and buy bitcoins.

Chargebacks are an extreme cost at the merchant side, and this extreme cost is added directly to the end product costs for honest customers. Single chargeback can loose the merchant thousands of euros, atleast in the case of Paypal where paypal might take the chargeback amount + another time the chargeback amount as reserve for costs of handling the chargeback. Even if you disputed successfully the chargeback there is upto 15% cost.

Now even at 7.5% cost, even if 0.1% customers do chargeback and you successfully dispute it 100% of the time, is 7.5%+human resources added to the final product price.

Computers are dead cheap nowadays anyways, 150-200€ for cheapest netbooks, new
400€ for full desktop.
That is less than any serious business would pay in TRX fees in any given month. Nevermind if they actually process the CC fees themselves there is also reserves etc. holding a % for atleast months, or for the lifetime of the merchant account.

Payment processing is currently *very expensive*, for example for us it accounts for roughly 6% of total costs! More than our marketing budget ffs.

If we'd solely use bitcoin, buyer would benefit:
 - At the very least 3% average lower service price, more likely in the 15% area (for 100% margin service, 1euro saved in costs lowers end price 2euros, 25% margin service price will likely stay the same)
 - No PP Dilemnas, getting verified etc.
 - No random payment reversals with PP and causing need to submit extra info to PP for validation
 - No sending utility bills, drivers license pictures etc.
 - Not having to keep a valid CC on file @ PP to be charged anytime for whatever reason PP decides
 - Not having the chance of PP employee stealing your CC information (In the past even cleaners had access to CC information)
 - No random accounts freezings
 - No waiting always PP to load forever (for finns logging in might take 3-7minutes, amazing it doesn't hit timeout)
 - Fast transaction histories if you need it
 - Ability to purchase sub-1$ priced services (PP Charge minimum 0.39$ TRX fee), in practice availability of good value sub-5$ services. Anything below 5$ and the TRX fee margin becomes too high
 - Some long term payment discounts on low priced services are transferred to even monthly subscriptions (TRX fee minimums)
 - Anyone could use our service, as in practice Bitcoin is available to any nationality without restrictions (Unlike PP)

Many have asked us to support WU, but we'd have to charge 40-60€ per transaction for using WU

I just noticed Z-Tex offers 2years warranty, while BFL is 6months, and Icarus probably case by case.
So i would think the MTBF is to be calculated around 4-5 years then?

So i did some number crunching and all of sudden Z-Tex actually looks promising when bought at lots of 10 (or more), if lifetime can be expected to be at least 4yrs on average.

Am i correct that it achieves now 225Mhash/s with high confidence? Or what should i expect as the average rate?

Using the fastest bitstream, under proper conditions, does the 2 year warranty extend to businesses as well?

Package contents include heatsink, usb cable, and heatsink?

the 4608 probably comes exactly from 7990 specs (?)
GTX 680 being the midrange, there will probably be a more powerfull GPU under the way, and with equal amount of SPs it might perform well enough to be a mining card.

My mining operation is rather small even after current upgrades, but priced at 15k $ i might be able to justify the cost come next winter, 25-30k $ definitively not.
Also depends upon warranty (and insurance terms) i can get for the device.
But if i decide to go for it, expect steady purchases for new ones every few months.

and yeah around 1500W is the sweetspot, can have 2x on 16A circuit. Then again, almost all industrial + DC circuits around here are 25A.
Some offices have only 10A. The gap can be filled with FPGA miners or Sngles

Difficulty does not factor into your operating costs, it factors on the revenue side. So irrelevant to somehow forcibly include into the COSTS side of things, when it's REVENUE side

But how does one factor power costs when one pays annually, basicly getting interest free loan to pay it once per year AND doesn't need any kind of A/C AND first 7-8kW usage for 10months a year is "kinda free" in the sense that it replaces (more expensive, heating oil costs more for heating purposes than plain electricity here, thanks to taxes) heating
Does the first 8kW have negative cost then? *whistles*

now after failed underclocking it reports 0 GPUs >_< ffs
and no files in ACTIVE/

** EDIT: Got it fixed

I'm Finnish, like i told you already, we use Euro, not Pound Sterling.
No, i'm not confusing. They do not accept CCs, only finnish banks etc. Even if you are Finn you can't get that price unless you are a company.
Because Finland has so insanely high taxes we get sometimes subsidized by multinational corporations. For example, many Germans come here to buy their BMW ...

I can sell you some cards for, say 500$ + shipping, i ought to have 2 to sell next week unless mobo, psu etc. for new rig arrives.

Doesn't look too bad soldering case imho.

I'll give 100BTC/520$ in PP for these if you cannot find a buyer.

PowerColor HD5850 Heatsink + Fan. Looks reference design to me.

Fan in good working condition. Heatsink quite clean despite running for a year (no i didn't clean it).
One of the heatsink screws got cut through while i was screwing it back after replacing thermal paste, so i decided to replace it with a AC TwinTurbo. All screws with springs are included however.

Pictures upon request, i already took pictures but it's a PITA to transfer pics out of my Nokia E7.
Shipping from Finland.

Price: Best Offer + Shipping.
Buy out: 25$

Payment PP or Bitcoin equivalent.

No finnish store sells in either currency ...

Sonny told me that they can be flashed by customers, and they are going to release new bitstream which should increase performance later on, and those will be made available for download.

It's a finnish store.

Unless you happen to be paying far less per 7970 than newegg pricing I get new ones for about 445$ incl. shipping, with interest free credit when purchasing them ...

Doesn't Raspberry Pi have some USB interface?
USB is backwards compatible on that direction too, i think.

Exactly like i assumed, that is pretty much double price.

I seriously doubt 7990 is only 33% more expensive per card. Try more like 80%.

7970s are damn cheap right now, well for me atleast ...
