So, if I understand this correctly, I can get any PCIe 3.0 x16 card and it will function properly without reaching a bottleneck?
I did not write that you could use
any PCI-E 3.0 card, I specifically mentioned the 7750. With that said, you could certainly install a more powerful GPU than the 7750 without fear of maxing out the PCI-E 2.0's theoretical bandwidth limit of 8GB/s. Just be sure you have a powerful enough PSU with enough PCI-E connectors(along with enough space to fit the GPU).
