Are these all 7950s? Based on the hashing these look like this GPU.

My MSI 270x’s will do .48MH\s

Actually, you can build a 2+Mh/s GPU mining rig that consumes roughly ~700watts with 3 undervolted R9 280X’s. The upfront investment in hardware is still there though :-\

Ah ok. I was just using conservative estimates. In Australia we pay an arm and a leg for everything. Computer hardware is no exception.

I’ve come across a Gigabyte R9 270 oc 2 gb edition for under $250 [url=http://www.sbtech.com.au/gigabyte-r927oc-2gd-amd-hd-9270-pci-e-3-0-2gb-256-bit-gddr5-card/]http://www.sbtech.com.au/gigabyte-r927oc-2gd-amd-hd-9270-pci-e-3-0-2gb-256-bit-gddr5-card/[/url]

It’s my understanding that they pull over 400khash/s… I just want to start off with a single or dual gpu rig for my first build, any advice you could give?

Ive got two Gigabyte R9 270x’s doing 410kh/s.

Just started mining with 2 machines I built
One running .82 Mh/s with two R9 270x’s and one .72 Mh/s with two HD 7850s.
