To put all the rig building cost comments into perspective:
I bought a HD5870 that generated just under 4 bitcoins a day, so I bought 2 more HD5870s and was getting 11 bitcoins a day. Ten days later and I am getting just under 4 bitcoins a day with all 3 cards. My rig was built on old and second hand hardware with three new GPUs and a new PSU for a total cost of less than £600. It costs £20 a month to run. I'll leave you to work out if its worth building your rig, but don't forget that the difficulty will probably have gone up again by the time you've got it working. The link below will shed some light on this:

what i am thinking of is buying a motherboard that will fit 3 cards at the moment, i dont know if i can clock these cards and get 275 to 350
lets say i buy 2 cards at first, then in a couple of weeks buy the third card, ill have those working for 1 to 3 months, then maybe sell like 50 or 100 bitcoins to help pay for second rig,
im just gonna have to figure stuff like this as i go
like how much do these companys buy bitcoins in bulk, what type of ram, or power supply i need?
stuff like that
pretty much the immediate goal is to break 1.5 to 2 gigs of hash's and be in a mining pool
