Everyone seems to be ignoring the fact that there is no such thing as a "scryptminer." There are graphics card yes, but no ASICS, which it sounds like you have purchased. Where did you get this from? What website? Also, I just mine coins myself going by their current value because I don't trust multicoin sites. For one they don't mine the most profitable coin because they don't mine every coin. They mine the most profitable coin from THEIR own personal list of coins, so yeah. I make a batch file for each worthy altcoin so switching take sme 5 seconds. That's just how I do it though but if you're new then perhaps a multipool is best until you get the hang of it.
That's funny, there are already asics for scrypt mining away and more coming up this year.
To the OP you will not get a ROI within 2 weeks, why 2 weeks anyway? Just mine away many different coins and exchange them for BTC, if you're smart with that many power you will definitely make some money.
Thank you, that's what I was thinking too. Just was wondering the two weeks, since difficulty rises so quick, I want to get one more GPU for it and leave it at 2.5MH. Then mine around altcoins, hoping to mine some unpopulars with easy difficulty and sell them on cryptsy. Then after I'm doing making enough cash, sell it back on ebay. Take the cash I have plus the money from the sold miner, buy a better miner. etc etc.
