Now i run my rigs for about 6-8 hours last night with BTC Guild pool with total of 4.78 TH/s but i only made  0.01590032 BTC. Now at that speed i expected a little more earnings.
There are also around 14000 miners in that pool for US but only 4333 for EU. Since im in USA, i was mining its US pool. Would it have been better to mine in EU pool? OR you would suggest another pool?

Please help out another n00b miner so i can become more fluent with this. Thank you for all of your help in advance.
