Nope? The TB3 connection provides 40 Gbps but the PCIe slot only uses 32 Gbps to follow PCIe specifications. Makes 8 Gbps leftover which can be used for peripheral stuff. Ethernet takes 1 Gbps, makes 7 Gbps left for the USB ports. Unless one is going to use only external SSDs with these ports, it's not going to happen that the bandwidth is used in a way that the GPU performance is crippled.

If you are talking about PCIe 3.0 X16, its bandwidth is 32 GBps instead of 32 Gbps you mentioned. Thunderbolt 3.0 is not as fast as you would expect compared to PCIe 3.0. Its speed is only comparable with PCIe 3.0 X4
