[SOLVED] GTX 1660 in PCIE1 or PCIE2 slot? Does it matter?

[Jaxstarke9977]

I have an ASRock B450m/ac mobo with a Ryzen 5 3600X CPU and a GTX 1660 GPU. The mobo has two GPU slots, one labeled PCIE1 and the other PCIE2. Does it matter which slot I plug the GPU in? Aesthetically I prefer the PCIE2 location but if it hinders the card's performance in any way I'd rather it stay where it's at in the PCIE1 slot. Thanks.

Always plugg your GPU in the first PCIe slot (closer to the cpu).
It has the maximum bandwidth which equals maximum performance.
The top slot is PCIe Gen 3.0 with x16 bandwidth.
The bottom one is PCIe Gen 2.0 with only x4 bandiwidth.
That is one the reasons SLi/Crossfire isnt a smart investment nowadays.
