Many thanks for replies, especially to @h311m4n for high effort explanation!

Now I see that radeon card is a "must have" for such a minig rig, and you all suggest radeons 470 or 480 but these cards are expensive... $200-250 for a card is out of my price range.

As I wrote in my first post I can risk (and probably loose ) $200-250 in total.

So what do you think about buying radeon R9 270 2GB for the beginning (I found one for ~$50), and mine with this few weeks and buy RX 470 or 480 as a second card?

This is how I see my build:

$50 - PU Zalman ZM500-LX 500W 120mm
$50 - Asus H81M-Plus
$50 - R9 270 2GB
$50 - CPU Pentium G3260 3,3GHz LGA1150 (or Intel Celeron G1840 LGA1150)
$20 - 4GB RAM and HDD

What do you think about this build now?

You need to think beyond your current budget/acceptable loss and hence, see my first post where I advised you to do something else with those 250$ ;-). As I explained in my first post, an R9 270 2Gb is a waste of money. Those older gen AMD cards consume way too much power and won't hash fast enough (especially a 270) to justify its purchase. Do not forget that the difficulty always increases for a given coin. Also, it's a 2Gb version so it will be completely unusable with GPU mining within very soon (imo). You could maybe gain a few zecs (i'm talking like 0.001ZEC) with this but it'll take you a lot of time, even if the difficulty is still low.

I would go for at least a 280 or 290 and at least 4Gb, otherwise your just throwing money away

Now, if you just want to learn about mining and see how the whole thing works, I guess if this is the maximum you can afford, then go for it. But be warned, mining tends to be addictive Grin

to be fair, a 270x can probably be found for ~$60 right now, and is making ~$2-3/day at zcash. so theres an okay chance it will break even before zcash/rthereum become fruitless to mine on it, but then what?

youll need a newer gpu to mine beyond the zcash bubble, and its tough to resell a $50 gpu thats had multiple owners and is ~3yrs old. youll be back at step one, but with a $200 rig that cant profitably mine anything and the cpu/hdd/ram probably didnt get paid off while using the 270x to mine (unless the zcash party lasts 2-3 more months)

follow everybodys advice - you need a $1000+ budget to assemble a good 4GPU rig that has a good chance of profitability over a 1year timespan. at minimum, $600 to build something with 2-3 decent gpus
