Hello,

I'm would like to start mining Litecoins (or any other profitable "Alternate cryptocurrencies") since there is no way that I could start Bitcoin mining. I'm going to do it as a source of alternative income as well as a hobby. I don't pay for electricity so don't worry about factoring that in to advice Smiley.

The max I can spend on the build is $765 USD

I really want to get the most Kh/s (or Mh/s) as possible, this said I'm fine with having 4 cards on one rig, or more than one rig is fine aswell!

Really what I'm asking for here is help with picking parts, because I'm new to mining and I don't really know what specs I should be looking for (besides no nvidia cards Cheesy).

I was recommended to start with a 7950, and add another later on but id like to hear other options and opinions to.

As always thanks in advance, and I'll be sure to send some LTC (or any other "Alternate cryptocurrentcy") your way when I finish!


Currently Mining: Litecoin, Xencoin, and Worldcoin (Just because its fun!, don't yell at me ;_;)

The issue with rig-building is that economies of scale is VERY, VERY important.

No matter what you do, you will have to pay $400 USD (or so) to get your basic components - PSU, Motherboard, RAM, CPU, HDD, and so on.

After that, it's all about GPUs and how many your Motherboard and PSU can handle. So for $700, you may be able to get 1 or at most 2 GPUs in a rig with a cheaper PSU.

Comparatively, for about $1,400, you can get a much larger rig with a lot more hashing power.

The 7950s are the best bang for the buck, period. I've run countless payback tests on every card on the market for LTC, and nothing comes close to the 7950 unless you can get free power and buy 5850s ad nauseum (they are about $90 USD and hash at around 300-350KH/s).

Right now, I have about $1,900 invested in my rig (5x7950), and I'm expecting about 2,750 KH/s on the rig, or over 1.5 KHs per dollar spent. On a $700 rig, that number will get closer to 1.0.

look at similar treads  Grin

but the big lines are :
small cpu, equal cpu ram to Vram
good powersupply

when many graphics cards use riser

no case or a case with lots of fans

use AMD cards, the 7950 is among the best new.

Im fine with lower hash rates for now, I can upgrade in the future but I dont have the money for a better rig, and wouldn't for awhile. I was planning on using the revenue generated from mining to upgrade. Also, I dont pay electricity Cheesy

the less price for the the most MHZ OC model or boost . Grin

As I said before
 when many graphics cards use riser and no case

no case : 2 or 3 fan model or
a case with lots of fans : standart reference model 1 fan that blows the heat outside
