My motherboard has three PCIe slots.
One is used by the graphics card, and another is occupied by a USB 3.0 expansion card.
The remaining one is hidden behind the graphics card and is vacant.
I am considering utilizing this hidden slot to introduce a 2.5 Gigabit Ethernet adapter to enhance my internet connection speed.
However, due to space constraints, I need to use a riser cable.
Since I want to avoid using a riser for the graphics card, as it may impact performance, which of the remaining devices – the 2.5 Gigabit Ethernet adapter or the USB 3.0 expansion card – would be better to connect using a riser cable?
I believe that using a riser for the USB 3.0 expansion card might also affect its performance.
If that’s true, I’d like to choose the option that minimizes the impact.
