lol..
i have 5 i5 core machines
terrible at mining scrypt, won't get more than double digit khash
2 XEON
same as above
1 antminer
that's not a scrypt miner. so that'll get you 0 khash
1 nvidia 8800GT....
please put that card in a museum, you're lucky to get triple digits khash out of those and I'm certain you'll pay more for electricity than it pays out in btc
a friend of mine using only a gfx card has more hash rate... and the card is nothing special 300kh/s...
because your friend isn't using the wrong hardware.
