PCIe Lanes - ashash - 02-14-2015

hi guys

as you know , each cpu has number of PCIe lanes

for the example , i7 4930k has 40 lanes

well , if we have 3 vga cards for example 3x r9 290x and if we want to run them as x16 , we need 3 * 16 lanes which is 48 lanes

as the result , we cant run all of the cards on x16 and we have less bandwidth for one of the cards

so the question is , does it affects oclhashcat performance?
i mean does oclhashcart use all of the bandwidth of pci express or even if we use x1 , it doesnt affect the performance atall
