TL;DR - Expensive cards run faster, ATI/AMD > Nvidia for mining, Radeon 5830 most efficient in their testing.
It's a pity this article didn't look at a few other cards which would have been very competitive, namely the Radeon 5850's and 5870's. I've found my 5850's do very well, especially considering the performance/watt ratio.
- AlexC04 15y agoI think there was more to it than that. It also came to the conclusion that a $130 video card (Ati 5830) can earn $540 a year. A system costing $1710 could earn $5300 per year. Assuming a $14 bitcoin that represents a 210% return on investment.
- mashmac2 15y agoThis, of course, is making a big assumption: that the difficulty factor will stay the same. It has consistently increased, making earning those bitcoins significantly more difficult. Break-even for me occured at about 75 days for my 5850's, but also used a much lower difficulty (less than 5% of the current difficulty) for the beginning of that.
