You probably need to install AMD OpenCL drivers.

0) More fan noise
1) EM Radiation, wont kill you, but will probably mess up radio/TV/wifi reception.
2) No airflow over the motherboard caps can cause them to overheat and catch fire.
3) Electrocution from small fingers/paws touching it.
4) Short circuit from dropping crap in it and the bottom touching something metal.
5) For god sake don't put it on anything flammable you could burn down your house down.

Bad points:


Wrong FPGAs are used in electronics and science they have a resale value.


About twice as expensive, but that's made up by the electricity cost savings you make.


Rubbish FPGAs are way smaller than PCs and graphics cards


I dunno how sticking it in a USB port and installing drivers is any more complicated than a PC graphics card and installing drivers.


He means SHA256, as far as I know only ASICs are stuck with what they're made to do, FPGAs are re-programmable.


That's because they are good at what they do!

Yeah last I heard MtGox had their UK bank account closed. Did they ever fix that? 

Litecoin solved this by going smaller.

Gold doesn't scale either.

Germany is expecting a 7 year transaction time to get it's gold back from the Fed 

Pools that are honest and upfront about charging 3% and pay daily PPS are generally much better than pools that claim to have 0% fee but then keep all the processing fees, namecoins and come up with some wierd delayed payment scam scheme.

You learn from experience.  

If the money cannot be given back promptly one has to suspect it has been spent.
If it's coming back in drips and drabs one could suspect it was spent on a mining farm and he's mining back the money.
If you use a pre-order to obtain a free loan for equipment or investment that is still a scam, it's called an arbitrage scam. http://en.wikipedia.org/wiki/Mail_and_wire_fraud

No 650w 2x PCI-E 6+2 will blow!

You need something in the 1000w range with 6x PCI-E 6+2 connectors.

People get scammed by charge backs so it's very hard to find a seller that way but you could try eBay.

The 5770 is a horrible card get very hot and dies easily.

5830 for same price is better than 5770/6770.

Did you get it from a shop or ebay? Is it able to run games? Are you using Windows or Linux?

You all remember that famous line from the film Jaws..

We're gonna need a BIGGER BOAT BitcoinX chart!!!

BTC95 and it's out of the top of the chart which stoped at 90. Now fixed.

There are no dangerous gases coming off your PC.  

E.U. even took the lead out of the solder to protect the people recycling components!

The smell from new electronics is flux and it burns off pretty fast and is harmless.

The biggest danger from running PC's 24x7 is dust build up which I've seen set on fire!

So keep the CPU, GPU and PSU heatsinks clean.

Pulling the dust out of the air is probably beneficial for health especially if you have asthma.

Just works, at least on 12.11beta, which is what I use with 7850,5830,6850.

Overheating?

If it's reliable time to failure you could write a script or cron job to do a system reboot every 9hrs.

or put a power timer on the mains electric cable.

Oh, come on, it was funny!

I don't know if Josh knows it but the customer he's replying to, Davincij15, has invested like BTC 3000 in pre-orders that would have been worth $267,000 at todays price. The guy deserve a factory tour to put his mind at rest at least after that much commitment.

LOL, owned by his own comment.

If you mined the bitcoins there is no capital gain in $ value but if you sold them you report the $ ammount as income.

If you bought bitcoins with $ and they gain in value then you have a capital gain on an investment to report.

USA also made all barter trades taxable, so even if you don't use $, you are still subject to tax if you barter for goods and services.
So even if you mine Bitcoins and spend them as Bitcoins you're not going to escape US tax!

Yes a higher fee will get your transaction processed faster as some pools to reject freebies transaction confirmations.
