I'm buying a PC with gfx cards just for hash cracking.
I have a budget around $2.5k (+/- $500). I read about HD7990 that this one like 2x7970.
1. Which is the better: 2x7990 or 4x7970?
2. Which motherboard supports 4 video cards? I read that the usual motherboard supports only 3 GPUs. And I read there, at this forum about PC with 8GPUs. But it was a server motherboard.
Thanks
