For building a GPU based rig, normally you'd need to spend about $400 - $500 on the PC hardware (MB, HD, Ram, Power Supply, CPU) before buying the video cards (up to 6 of them on an average system). each card is going to be about $250 - $700 depending on what you go with.
For a grand theres a couple choices; buy a used gaming pc from a couple years back if you can find one for a couple hundred bucks and just add GPUs to it. might start with 2 decent ones, then make some money off of them to build a better / more complete rig later.
The other option is to buy an older generation ASIC miner like the S7 which you might be able to get for 6 - 800 and would be plug-and-play but will only work on BTC.
If you want to actually make money, it might be better to invest the 1k into trading currencies for a few months and see if youre able to make enough to build a more complete solution. That will also let you learn the different currencies, and learn the process for transacting with the various coins and wallets.
Asic miner works only for BTC ? not in other coins?
Which miner will be best for DASH?
trading I hate. I don't have time for trading.
LoL,
You don't have time for trading? What makes you think you have time for mining? I have been working with computer for over 20 years and have a degree in computer science. Every time I change anything in my rigs its a circus. Sometimes its a circus when I don't. There are forum after forum (this is only 1) with thread after thread of people trying to get up, running, and stay running. It is time consuming.
Most of the people mining started mining when the returns were much higher. The same equipment that was making 20-30.00 a day is now making 10-12.00 a day. It certainly may have been worth putting a rig together for 2000.00 when you were getting 30.00 a day because you would make your money back in 2-3 months. Now its going to be closer to 9 months to a year (if at all). That means you won't make a penny for 9 months to a year, and may never make any money at all. Sounds like a great deal to me!!! But that is the current situation.
If you want to get into mining, I'd be trying to do it as cheap as possible. That means NO NEW GEAR. My son and I started mining with a few (2) 970s we purchased used for 200.00, a cpu/mobo we picked up for 30.00, an old hard drive, and 15.00 worth of memory. There is no need to spend a lot of money (and most likely a bad idea) to get started. Some people even have the parts laying around. You just need a computer with a video card.
Get the minimum and see if you have the tech skill to get it running.
From there, you can start adding and expanding.
Start somewhere rather than trying to get everyone here to do all the work for you, we can't. Get a computer mining and start asking specific questions (after using the search on the forum). No one here is going to be able to write a book for you on how to start mining.
