Hmm yeah.. what a fun gamble though.  Plus if LTC completely blows up im left with a top of the range card .

The way I'm looking at it is the 7970 at current (pool) mining rates gets you 2LTC per day.  That pays itself off in 8 weeks, based on current market value.  Now the question is, can I mine enough in the first couple of weeks to *fingers crossed* future proof myself against a sudden rise in difficulty, which will lead to a rise in price and therefore those coins should cover me...at least (hopefully).  Basically I hope I'm not too late getting in there .  Glorified gambling, this shit is so addictive.

Will be a fun experience anyway.  An experience I can carry on to other cryptocurrencies...
