Hey guys,

I want to join the Bitcoin mining horde and what hardware I am thinking about buying is this Butterfly Labs' 600 GH/s card http://www.butterflylabs.com/monarch/

Is it a good investment right now? Is this site calculator any accurate http://bitcoinwisdom.com/bitcoin/calculator ? It shows I can get back my money (new price of the card is $2196 instead of $4680 as shown on that website) in less than 20 days if I start now. If all the numbers are true or close to what I will get, it is darn good investment for a Bitcoin newbie like me.

Thank you all for your inputs.
