Hi all,

Ive build my first rig 1 month ago.
Im mining dodgecoins with 3 sapphire radeon 7950 with a hashrate between 1500 and 1600 kh/s.
Im thinking about building a new rig with 4 cards.
The videocards that i want to buy are the radeon R9 280X. I want to know which one are the best in terms of hashrate, powerconsumption and noise.
1) Asus
2)Gigabyte
3) MSI
4)PowerColor
5)Sapphire
6)Other one

And whats the best MOBO you can buy to run 4 cards on it.

Cheers
