Ok guys, thanks for your reply's.
Im going for 4 asus 280x cards. Im going to run them on an asrock 970 extreme 4 mobo with 4 riser cables (2 powered). The only thing that i needed to know is the psu. I want to buy an enermax platimax 1350W, is this enough?
Thanks in advance.

You will want something a little larger than 1200. You can use a 1-16x riser cables to use one of the PCI-E 1X slots on the mobo. No way you are installing 4 cards directly on the board.
Thx man for your quik reply.
The assrock extreme 4 has only 3 16slots, where can i put the last card?
And a corsair 1200 watt, is that enough to run 4 cards, or do i need more.

Hi,
I got some experience with different 280x cards. Tried to tweak them as much as possible - still some room I guess, but they are stable....
All on Asrock Extreme 4 (dunno if this is the best, but a lot of ppl use it, its cheap and has an external power switch)
- 4x MSI Twin Frzn (they do 750-760 kH @ 0.99v undervolt)
- 4x Gigabyte Windforce (they do 750-760 kH @ 1.08v)
- 4x Sapphire Vapor (they do 730 kH @0.99v)
- 4x Sapphire Dual X OC (they do 730 kH @ between 1.05v - 1.2v)
--- no clue about Asus and Powercolor
Imho best cards from this set are the MSI. I would not recommend the Sapphire (especially not the Dualx X OC), they have problems with heat... some kind of autothrottle in case of higher temps... even with good cooling and tweaked bios I can not squeeze out more than 730/740 kH.
Hope that helps
Cheers
Edit: Another important information. All systems draw around 1100-1200 W @wall with a gold/platin PSU - you need at least 1200W PSU

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
