Title: Opportunity costs of used vs new video cards?
Post by: stickman on May 05, 2011, 04:22:38 PM
With all the buzz lately over the increase in difficulty and people expanding their mining setups, everyone seems to be recommending still that everyone buy USED video cards on ebay for cheap rather than buying NEW cards.  My question for everyone is do you really think this is the best idea?  Right now at 2.5GH/s I'm pulling in around 20-25 BTC a day on deepbit, and given the current exchange rate of BTC to USD, I'm starting to doubt the need to buy used video cards.  Buying cards on ebay means waiting and often losing, and that's time I could be mining.  Also, if I buy a used card towards the end of its warranty of past it that fails, I may just be out of that cost rather than having the ability to RMA the card.

Anyways, thoughts?  Opinions?

Thanks

Are people really thinking about starting a new mining build after looking straight at a 50% difficulty increase from now on? Then I guess we are one more forum guide away to make it a 100% jump each time. You might as well wait a little more because when everyone is selling, it will be so much cheaper to buy.
