im new to the digital currency scene. Im very interested in bitcoins and litecoins. I know about bitcoins a couple of months ago and how foolish of me not to invest in it.
Anyways, im interested in bitcoins now. this is my setup:
AMD Phenom II X2 550 3.1GHz (unlocked the 2 cores so bascially a quad core at 3.1Ghz)
4GB RAM
9800GT
Im actually thinking of setting up a bitcoin rig, which has 2x 7850's but im really unsure about how much power that will use and what power supply i should buy (e.g. 600W or a 700W etc). Ive seen some videos on youtube about mining using the 7850 and this guy was mining using 2 7850's and he total power was about 850W which is pretty crazy (he did overclock and things like that). Im planning to mine on stock hardware meaning no overclocking so how much power in total do you guys think that will take?
So should I go for that rig with 2x 7850's or is there a better rig I can come up with that will use less power? (My budget is about £400. This includes the power supply, cpu, ram etc). Also, would it be better if I just buy the bitcoins directly rather than mining them?
Also, I saw a ASIC bitcoin miner on a website (forgot the website name but it'll be on my history) which mines at 38GH/s, uses 300W and costs $800. Does this seem a bit too farfetched because it does to me. And i plugged in the values to this calculator:
http://www.bitcoinx.com/profit/and it says i'd get a profit of 3328$ in the first 12 months(my price per kWh is £0.16 :O
So in my situation, which would be the best bet? Mine through GPU, ASIC hardware or just simply buy the bitcoins?
