How much could i get with an hp pavillion 1000a thats been sitting around forever, my real mining comp gives only 12mhash(i kno it sux) , the graphics card on it is a nvidia 7300e and the processor i already know should give me 1-2 mhashes
p.s already looked on the wiki.
"Is it worth it"?
No. At current difficulty, you could buy off the exchange for less than you're paying in electricity and wear/tear in mining.
