Hi Guys,

Just noticed that difficulty has jumped to 1.69M.

I've just purchased an ATI 5858, which I hope will give me approximately 300 MHashes/S.

Where does this leave me? Am I wasting my time now? Also, is it the case that difficulty increases/decreases with the number of coins being generated per a 2 week period.

If some people stopped mining would it decrease and also if it comes to the stage where no new people being mining will the difficulty remain static?

Cheers Smiley

The difficulty is adjusted to try to keep the time take to generate a block at about 10 minutes. So difficulty adjusts according to changes in total hash rate or stays the same if hash rates remain constant. This is not necessarily linked to the of number of  new people, since existing miners could upgrade equipment, or drop out or newcomers don't use dedicated rigs so don't add significantly to the hash rates etc.

I hate to discourage anybody from mining. 

But being realistic, I started mining when difficulty was around 250,000.  I quickly realized that the return was going to be very little on my hd4870 and hd4670 that I had in another system.

With a single card, you aren't looking at any huge returns.  And hey... maybe we'll see a huge rally in the near future Smiley

You're still getting more of a return now with one card than early adopters were getting back when you could mine a few hundred (or even thousand) BTC per day with your CPU.

Really depends on the "single" card Cheesy

The cost effectiveness of the 5850 could still make it worthwhile depending on his electrical costs.

That's true, the 5850 is a fairly cheap card..

Also, my electric costs aren't really that high tbh, i'm even thinking of installing a heat exchange unit into the server room so I can offset my heating costs with the heat produced from mining.

I agree I run multiple 5850's really good cards and can be seriously OC'ed for some very good Mhashs, I avg around 330 - 350 and you can get more but I want to OC my cards too much.

I OCed my 5850 to 970/325 and am getting about 400mh/s.

I third the 5850s.  They strike a good balance between the low hardware cost of a 5830 and the mining power of a 5870.  Add into the mix that they are lively overclockers and relatively low power and you have a real winner.  They'll run well at very low voltages and happily give you 300 MH/s while being pretty cool and quiet and they can perform when needed (I've managed as high as 461.1 MH/s for a continuous 3-hour block).

One caveat is that the popular Sapphire HD5850 Xtreme cards have less than perfect fans (cooling is great but the fans are fragile).  Avoid running them at 100% 24-7 and you should be golden.

Arguably, with the difficult and market rate where they are, this is a fairly good time to buy.  If there are other reasons driving you to mine then you could do much worse than putting a single 5850 in an already 24-7 machine.

Looks like I made a good choice so.. I've just secured another 5850 that has been super clocked etc and has insane aftermarket cooling/rad on it..

between the two cards I should prob hit around 700 MH/Sec.. Maybe more..

Now to get a PCIEx converter extender.. Smiley

Also, i'm aware of the risks involved so it just happens that I'll have to kickass cards to play battlefield 3 on.. Pity it's my server MOBO that supports Crossfire and not my desktop Sad
