Which of the two setups would be likely to perform better, 4 290Xs in CFX or 2 295X2s in CFX? Both yield 4 GPUs for the count, have nearly the same clock, TDP, price (per GPU), and memory (per GPU). There's not a single difference I can catch, except that the 295X2 performed slightly lower than the 290X in PassMark (because PM doesn't recognize dual-GPUs). Does anyone have any evidence one way or another?
