"That's impossible. What you're getting is probably 1600 kilo hash which is only 1.6 mega hashes which is nothing.
I'm shocked at how 90% of the people here can't tell the difference. 1,000 kilo hashes is just 1 mega hash. The best ATI card at frys, the 7970 (they don't yet carry the 7990) only does 600-700 kilo hashes. And when you run these cards together you lose efficiencies.
Most people here are reprinting 1,000 fold higher hash rates with inferior,lesser cards than the ATI 7970. What you guys are getting is kilo hash rates, which are 1,000 times less than mega hash rates so just divide what you think you're getting by 1,000 and that's your real hash rates.
Basically all the guys here saying they're getting 300m/hash are getting 300 kilo hash, which is like a new ATI 7850 video card which is a great card. You double that down in a new $1700 rig and you lose efficiency and you'll get at most 500 kilo hash with a dual ATI card and a high end CPU and MB. That's the rig I had and I took it back cause it was worthless.
The days when you could mine bitcoin or even much lower difficulty coins like litecoin with a desktop are over. You now need giga hash rates to get anything.
If anyone has any cheaper and easier solutions please share. I'm new to this and I've yet to be able to mine 1 full coin. Thanks in advance."
I recently built a mega computer from Fries. I spent like 2000 dollars and got a great motherboard, a hexacore AMD cpu, 10 gigs of ram, the works, this thing was blazing fast I mean. I took the liberty to throw in 3 graphics cards running the 7669 chipset. Well guess what, I was getting like sub 500 KH/s KILO HASHES, which got me like .2 BITcoins after about 24 hours of running it with the cpu and gpu screaming at overheating speeds, by the way, at current prices I just about broke even on the electricity spent...
As far as BITcoin goes what I would suggest at this point in time, as the difficulty has increased quite a bit over the last six months, I would recommend cloudmining. find a good site that sells time blocks for a yearly service fee and start mining away!
