HELP! Talk me out of buying more GPUs!!!

[Damnsammit]

I know this has nothing to do with mining but you could join a PC gaming forum and build yourself the ultimate gaming rig or rigs and sell them for double what the rigs cost you.

Wait, what?  Building PCs is so easy... people pay THAT much of a premium for a prebuilt computer?

I looked a few years ago into making that a hobby/business, but it seemed like the mark-up just wasn't significant without a cool custom case a la Alienware.

I'd say skip the 6 series and get some 7 series cards.

I've got 24 7970s and 7 7950s, and I sill find myself looking for deals on local classifieds for more. I'm addicted.

I'm looking at newegg and tiger direct to find the best deal on 7950s.  eBay is ridiculous, 7950s are selling there for nearly new prices.

BUY BUY BUY!!!

Yeah, I'd advise NOT going through ebay for new cards (though, great for ancient cards like the 5xxx series).
Main reason would be, you don't get the rebates, free games, accessories, warranty, etc. You can just sell the games for a few bucks and it'd be a better deal new than used on eBay.

Its not profitable sadly. Unless you get amazing deals on components.

There are a few companies that have made it doing it this way but I have tried and the margins just were not there.

I did however take my old mining rigs. Spend $100 upgrading them and sell them for close to my purchase price. After the components had payed themselves off of course. I had picked up some budget low power phenom 2 x6's for $90 each. Those payed for themselves with YAC alone mining the first 3 days. Then my 5850's payed for themselves mining CHN and FTC in the first few days. I just went out Bought a bunch of cheap motherboards 4Gb ram per rig. 800w power supplys, semprons and a ton more 5850's. 4 cards per rig. Undervolted and slightly overclocked 1.4Mh (scrypt) per rig

Now im upgrading the cpu, downgrading the PSU, buying cheap cases and selling half as 2x5850 with a 6 core for $500 to buy some 7950 rigs

I am not being sarcastic when I say its the size of my thumb  

You must be new to this subforum.

[rafsoaken]

just negotiate 400 bucks and you'll be fine.

Sure, I could just sell the GPUs when I get tired of mining, but that's money that could be in my bank account now.

Yes, LiteCoin will eventually go up in price, so mining as many as I can now could pay off nicely later.

LiteCoin might eventually go up in price, but there is also possibility of going down in price.

GPU mining is pretty much Dead. Its all Asics now.

An given comparison.

You can go and spend $45-$55 per Usb Block Eruptor in the Bitcoin market.
And it will yield you about 333 Mhash/Sec. They consume 2 watts each
and the size of your thumb.

Now you can go spend $300 pick up a HD 7970 at rates of 600 Mhash.
Alt mining is generally ~300% profitability, sometimes more.
http://www.coinchoose.com/

600 *3X(Profitability of scrypt) = 1800 Mhash equivalence at Bitcoin mining.
So its like 1.8 Ghash in equivalence basically for $300.

333*6= 1998 Mhash.
2Watts 6=12 Watts.


So you get more Hash rate, About 15 times less power, silent.
Size of your thumb, and its just more convenient.

GPU is DEAD. You need to move away from it.
And switch to Usb block eruptor if you want to continue mining.
And even so there are even more efficient mining ways out there.

You're missing something important. Is the 300% profitability constant? or will it increase over time. For example lately LTC is hovering around 900 difficulty lately, not changing very much. it's possible that you can still mine about the same ballpark amount of LTC in 6 months as you do now, however the BTC difficulty is going up like crazy, you will definitely get much much less BTC for GH in future. Food for thought.

In summary: Dear everybody doing mining maths, the mining numbers right now can not be use to calculate future profits without taking into account changes in difficulty.

A box from Newegg showed up yesterday with 3 brand new HIS Ice-Q 7950's in it.  $703 total !

hehe, good luck. I've had the same GPU addiction for years, however cooling costs are what have prevented me from completely filling my house with rigs.

I have partially solved my cooling issue.

I took an old trunk, like the kind your grandma keeps at the end of her bed and fills it with blankets and stuff. I attached a furnace blower (squirlcage fan) from a fullsized house furnace. I then stuck my 2x milkcrate rigs inside. I have a hole in the opposite end. It pumps so much air its crazy. I put the hole thing out on my porch that is pretty open, lots of windows. Even at 100f outside the hottest card is only 83c and the coldest being 64c.

I'm going to make some custom mounts with 1x1s in the box and put the components directly in the box, this should allow me more cards and more boards. I'm thinking I could put atleast 12-15 video cards in that old trunk and keep them all below 85c at 110f outside.

My ac went out so I had to macgiver this shit.

Yes, those barrel fans will move air like a 'MA!

(barrel fans, squirrel cage fans, furnace fans, etc - same thing different names)

Lotsa volume!
