This is what my motherboard allows me to do. Would there be a bottleneck issue solely because of the PCI-e slot?

By the way, any motherboard in the range of $200-300 allows PCI-e 3.0 x16/x16?

The skylake cpus only have 16 pcie lanes, so x8/x8 is the best it can do, and it is perfectly fine. Its not a motherboard limitation, but a CPU limitation. Lots of benchmarks dont show any difference between the two. Now if you had to run it at x4 youll start to experience a drop in performance. Right now the only ones that have more pcie lanes is the x99/2011-V3 HEDT platform. Dont worry about running sli at x8, everything will be good.
