I`ve sent like 26 btc, and waiting already for 40min, and it isn`t approved still, is it ok?

Can somebody explain why some pools take no fees at all? How they pay for their servers.

Personally I`ve got best results on deepbit with it high fees than on other pools. So maybe there isn`t no fees at all, as pool owners say in their topics?

I built my first rig and got noooby questions.
Is that okay that
1-hashrate jumping from 340 to 360?
2-when I move mouse it decreases very much to nearly 100

Using win7, thinking maybe 1gb ram not enough? Or how gpu connected with 2d (moving mouse, clicking buttons etc)

I`m really tight on money building my first rig. And it will be on sempron 140, with cheap ram and hdd.
And I don`t know yet, will I get 4x 5830 or 5850. I googled, and 5830 use 171wt and 5850 150wt.

How to count how much energy mobo and hdd needs? I realize that gpus need 150x4 wt, but no idea how much energy other stuff need.

I read a lot of forum, and gonna build my first rig. And just to make sure want to ask. Is that possible to buy mobo with one PCI-E x 16 and with expanders make 4 pcie slots, so I can plug 4 cards. And as I understand it is not important what bandwith got pci-e for mining, so expande PCI-E x 1 should be ok for mining?

Решил строить лошадку на 4 5850, и возник вопрос если будет плата с 4 pci-e но без поддержки кроссфаера, можно ли их все будет одновременно запустить (для каждой видюхи свой майнер)? Или виндоус просто откажется их видеть?

Существует ли java скрипт автоматически создающий воркеров и позволяющий майнить на свой кошелек с помощью GPU?

Где можно найти java скрипты для сайтов? Пока нашёл это http://www.bitcoinplus.com, но 19% комиссии слишком много
