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.

TB3 bandwidth provide 40 Gbps is only about 5 GB/s and PCIe 3.0x16 is 32 GB/s.

IMHO it's better only use for GPU.
