Hello eveyone. I would like to start litecoin mining. I have about $550 - $570 to spend on a rig. As you can imagine I want to get the most mh/s (or is it kh/s??) for the price I dont need a case or HDD (I'll use a flash drive + linux). Thanks in advance!

And hello to everyone on the forums!

Is there any advantage to actually doing them in crossfire? Why not just independent?

Has anyone sat down and done the math behind what $BTC has to get to in order for buying a rig to be profitable?  With the massive increase in difficulty that ASIC miners can fuel, I'd imagine it would be extreemly high.

Single card is good too. The real luxury of a well configured crossfire system, is you have a card, if one fails. Or you have flexibility to sell one, and apply it to some kind of upgrade.

The question wasn't as much about what is the smartest design(which varies for the users knowledge and situation). The question was more about what parts to work within the budget. $560 is tough, because you're right below a FGPA price range in the same has territory, and under a single card setup that would get you a similar hashrate.

There are a few sites that allow you to plug in numbers and give you a good idea of expected profits. Of course, the ASIC mining anticipation makes it hard to predict exactly what will happen when availability and costs are better, therefore most of the estimations factor in what is on the market now between all of the different methods and current farms/ASIC/CUDA/openGL...

Just because you have two cards, doesn't mean they are in crossfire. Hense, my question. Is there any benefit to having them in crossfire? My understanding is that only helps out with framerates on a single monitor. (If you run dual monitors, I think its better to not run them in crossfire).

When I was GPU mining on Linux, it was much better to *not* have them in cross fire, but that was 18 months ago. You can have multiple cards in a system with crossfire disabled.

Would it be possible to get up to 600 mh/s in my price range or is that pushing it? I'm fine with 4 older cards, just as long as they pump out a good hash rate.
