2 pcie slot, which should i use?


doesnt say anything, only how to install by a image ;(, btw the mother is the asus formula ix, and right one i have on the farest pcie of the gpu, maybe is the same peformance is both?
 
The top slot is the only one that will run at 16x. The 2nd(middle slot) will only run at 8x when populated and the 3rd(bottom slot(only runs at 4x). So technically the top slot will off the best performance, but(depending on what gpu your are using) there will be little to no difference between a 16x 3.0 slot and an 8x 3.0 slot.
 


i have gtx 1060 of 3gb evga, should i change it to the top one ?
 


With that card I doubt you'd see a difference. But the only thing it takes is a bit of time to see if there is any improvement.
 

on what can affect if is x8 or x16? performance in generally ?¡
