Just wanted to check if I generally understood this correctly.
I have X99A SLI plus motherboard, 5820k cpu and 2x970GTX in SLI. I have nothing else connected.
I tried putting those two cards E1 and E3. Everything worked of course, but as I run couple of benchmarks top card started to heat up much much faster, reaching 85 degrees very fast.
I then decided to put second card in E5 (so E1 an E5). Nvidia inspector shows that both cards are now running at 3.0 x 8.
However temperatures are now equally low, and there is 0 percent loss in performance in any benchmark software.
So I was wondering, since these two cards supposed to work in sync, is there ANY benefit in having one at x16 and other in x8 while they are in SLI?
