Adding a PCIe - USB Type C card

[CJoshuaV]

I have an ASUS ROG Maximus VII Hero MB and I'd like to put a USB Type C card on it. (I was thinking about the Gigabyte card.)

Right now the only card I have on the board is my 980Ti. If I add the USB card, will that split the bus in any way, slowing down the bandwidth for the GPU?

Thanks!

Hello,
short answer: probably not
Long answer: it depends on how many PCI-E lanes you have available from your CPU. Which CPU are you using? do you have an Intel NVME SSD or M.2 SSD (they take up PCIE lanes)? The USB card you picked out looks like a 4x card. Most graphics cards do not see a performance hit from 16x to 8x PCIE lanes... learn more about them here:

The CPU is a 4790k. I didn't put an M.2 SSD on the board, since I didn't think the performance gains would be significant over the SATA SSD (since it's not an NVME slot).

I may move the OS over to an M.2 eventually, though.
