Had a 4gb stick of ram and a hdd/usb stick laying about so no cost for those
After messing with this for over a week and finding I had a faulty psu, and gpui 0 not wanting anything higher than -i 18 without crashing. I finally have it up and running stable with just tweaking the TC. As you can tell by temp I have quite alot of room for OC. I believe I can have this at 1.2Mhs after fully tweaked. I'll keep you updated.
Just thought I would share for anyone interested in getting started with a cheap alternative to the single higher hashing cards. If I can get this hashing at 1.2+ that would be the same performance of 2x 7950, at about half the price, and you already have everything else. GPU pricewise its about 1/3 spent on gpu's for same performance.
