Hmm would it help prolong the life of my cards if I underclocked or throttled them? As I said I'm not looking to make a living out of this. if I can mine 1 bitcoin a month out of the two of them working together it will be good enough for me.
Yeah, no. Those two cards together get you like 400 Megahash/s IF they're perfectly configured and running overclocked. With ASICS coming online, tbcoins scenario is rather likely. So you'd be lucky getting 0,0001 coins a months.
D: yeah okay I might rethink using some of my other skills and just doing business in BTC then. Thanks for the info people.
