Congrats ^ lol
Does system ram matter at all for a gpu mining rig? Assume linux as the OS. I figured 2gb was enough, not sure if it hurts or helps the mining though.
How does a quad 280x mining rig for oh, roughly $1500 sound? Is that a worthwhile investment?
Is it possible to calculate the LTC difficulty rise? Maybe someone knows of a calculator for it, or is it something like this...
Difficulty increases every 3 days, at roughly +300 per rise. Would that be a good rough estimate at all?
So many questions
No, but what you mentioned seems about right. I'm not sure what's best to mine, but if there are more profitable coins I'd go for those and maybe put those into LTC as speculation.
I'm not sure how exchanges work exactly, but I plan to mine quite a few different coins and leave offers open so that when the price spikes (which happens a lot) then they sell, and that way I hope to keep profits above $100/day (on 6x290s with a theoretical 5MH/s rate).
