Hi

I'd like to share my plan with fellow miners and would like to have some input from those who are already mining with 4 dual-slot graphic cards

I am putting a Rig soon, I've obtained
4x 5830
1 Corsair AX1200 (1200W, 6(6P+2P)
1 old 160GB SATA HDD

I'll be needing a Motherboard and a CPU and a Case

My goal is to install either
4x 5830 (244MHash/s x 4 =~976MHash/s) (160Wx4 total 640W + system overhead, 4(6P+6P))or
2x 6870 + 2x 5830 (244MHash/s x 2 + 272MHash/s x 2 =~ 1032 MHash/s) (160Wx2 + 155Wx2 = 630W + system overhead, 4(6P+6P)) and later
3x 6990 (670MHash/s x 3 = ~ 2010MHash/s) ( 350W x 3 = 1050W + system overhead, 3(8P+8P) and ultimately later
3x 7990 (unknown Mhash/s and Power requirement)

With existing Motherboard and Power Supply(might have to change)
My ideal candidate for
MB : MSI   790FX-GD70 AM3 790FX DDR3 4PCI-E16 CrossFire (8x + 8x + 8x + 8x)
CPU : AMD   Sempron 140 Processor 2.7GHZ Socket AM3 1MB L2 Cache 45W Retail Box
Case : ( know I need a true 8 slot case, not a 7+1 case, 9~10 slots case is fine too, try to keep cost down, can afford have 1 side panel open the entire time.)

Thank you for reading this post, much appreciated if you can enlighten me!

just use a cheap motherboard with enough pci-e x1 slots.

It is pitch black. You are likely to be eaten by a grue.
