So what's the current best combination up to 200W if you have all the other components? I could fit 4 more cards into the MB.
4x GTX 750ti...
Can you run them on 1 PC with ATI cards?
Best to run one type of card, either all AMD or Nvidia, mixing doesn't always work too good.
I've got 6 270 hashing at 4260 mh/s pulling 740 watts from the wall. Under volted from .085-.095 mv.
About 10x GTX 750ti can hash the same rate, but at 340 watts OC'ed.
