Deepbit calculator says that you have to run about 500 Mhash/s to earn 1 BTC /day.... but! in less than 100 blocks difficulty will increase

using estimated diff, it only goes up to 554mh to earn one coin, so not to much of a decrease in coinage a day

mmm... diff will increase at 30% approximately.... 500mh+30%=650mh... not 554. Or i calculate something wrong?)

thanks everyone, what kind of bitcoins are you pulling in each month with these setups? Also how important is cpu power for mining, or not at all? What I'm asking is should I dump as much money as possible into video cards and disregard ram/cpu, or is there a certain point where that's gonna hold me back?

Here is some of the hardware I'm using. Please don't buy it out:

2 case fans ontop of 2 5830s and a $17 80GB HD

The only problem I had setting it up was that, without the ATI drivers installed, I couldn't see a cursor. If you can't install the ATI drivers without a cursor then you fail the first test :p GL

I'm liking the look of this build ^ but I'm thinking I may want to scale up to 4 cards at some point in the future, I'll worry about a power source at that point but what would be a good mobo for this?
