Right around where I predicted. Hash rates couldn't double so quickly because there aren't enough cards available in circulation.

BTW I'm using 5000 difficulty as the calculation point for profitability, since I see that as the hard ceiling based on available cards in circulation.
 
I just pulled the trigger on a 7870, as I'd been planning on updating from my 7750 for some time. Primarily want it for madVR and some demanding emulation, but with the recent cryptocurrency boom, maybe I'll be able to make a few bucks with LTC or altcoin mining. Not expecting to get rich by any means, but some offset of the purchase price would be great.

Does anyone know if LTC mining on the GPU stresses the VRMs? The 7870 I selected has the stock 5-chip layout (three ICs on the top row, 2 on the bottom) and I don't think they're heatsinked. The HIS blower should put some air over them, but I'm not sure that will be enough.

if it makes you feel any better, I've had 12 6950's running 90C+ for 2 and a half years, and the only failures have been fan failures.
 
If the fan fails the card can fry. I've had it happen to me before when a stray wire got caught in a fan. My 7970's rear fan also got so squealy and super-noisy I knew it was on the verge of failure, so I sold it to someone for cheap telling them it was suitable for watercooling (reference PCB) or for swapping out the air cooler.
 
Difficulty 2218 and rising.
Network hash rate 72 GH/s and rising.
Bitcoin and litecoin value in USD dropping 25%+ in one day.

There are going to be some disappointed people who paid $500 for a 7970...

As with any gold rush the majority of the profit is going squarely to the mining equipment providers - in this case PC parts makers like AMD and resellers like Newegg. As well as the people flipping 7950s and 7970s on eBay.

Honestly, I'm fine with that. Nvidia had their whole thing with F@H (it's still going atm), it's good and proper (lol, a phrase I learned from Latin) to show AMD some love this time round.
 
Looks like my R9 290 won't be here until monday. I really don't care for a profit but it'd be nice to have it pay for itself.

Hey, at worst you will make a bit of money when ur not gaming 😀

I have already made over 3 lite coins with this card, which is almost 100 dollars.
 
It will, LTC will bounce back up and easily exceed the $48 it hit before... This is the way crypto works really, as long as you aren't selling as you mine it's generally much bigger profits than what a calc will tell you.
 
Giving myself a crash course in mining litecoins with the rig in my signature. I'm only getting about 158 khash/s with it though, where charts indicate I should be around 260. I tried googling settings but came up empty. I'm using GUIMiner - scrypt alpha.

I'd try CGMiner 3.7. Also, if it's your only GPU, you'll get a lower hashrate whenever you use the computer, even the desktop. scrypt mining is also highly dependent on vRAM speed (the higher the better) and the proper core speed for said vRAM speed. For example, my highest hashrate is at ~900MHz core when my vRAM at 1600MHz, if I go higher with the core, my hash rate goes down, if I go lower, it goes down.

Did you get a 290/x?

You should get MUCH more than that. I get roughly 330kh/s with barely overclocked 5850.
cgminer 3.7.2 is what you want, and you can follow this guide for some basic settings.

P.S. The most important settings are
- --intensity (I found 14 to be the sweet spot when you can still use the PC, and 18 when not present)
- --thread-concurrency (it seems like you really should make it a multiplier of the amount of shaders)
- to some extent --worksize (everyone sets it to 256, but I get consistently higher rates everytime I set it lower, so 64 it is for me)

Is here. I'm seeing several thousands of BTC being moved for lower. The big players are dumping...waiting for my time to pounce.

Bitstamp is @$600 USD and falling.

Edit: Stabilizing @600.

Selling my 7950s if anyone is interested, up swing after the dump should exceed previous highs so stick it out. I mined when they were $2.50 😉

Now is the time to buy in with cash 😀

Lol. Someone realizes selling mining equipment is more profitable than mining 😉

I'm not gouging for price. That said it makes no sense to sell my caeds, I only am because the girls don't like me mining.

I'd rather keep them mining and get a new card for gaming, but the choice wasn't mine to make.

The crash we ALL saw coming happened.. now, the JUMP afterwards, how high will it go??

I'd guess $60 for LTC.
 
I'm fairly new at this and all i can say is.....Thank god it's Friday night, my favorite color is red and I'm darn glad I'm drunk!
LTC = $19.77 USD 😱
The only thing going up today is my electricity bill!

EDIT: LTC = $17.76 USD now!!
EDIT 2: LTC = $16.60 USD now..... I'm putting less ice in my next drink! :'(
