I tried finding an answer to this one but I failed.
I am planing on building my PC soon so I started doing research on what components to buy, prices to compare and so on, I already decided the CPU option, and now it’s time to compare which motherboard should fit my needs, The offer is huge and is rather hard to find the best choice and ballance between price and features.
And so searching for one I came accross a concern about something,
For the sake of conversation, the PC will be devoted mostlly to gaming, not 4k HDR or anything that fancy, but a regular gaming at 144Hz* @ 1440p or so.
*This is the monitor I intend to use, the fps rate doesnt have to be 144 though a 60fps should suffice.
The processor of choice is AMD Ryzen 5 2400g with VEGA graphics, I am looking to get some buget friendlly configuration.
But back to my question, so, as I searched for a motherboard with AM4 socket for mentioned CPU, most of them are multi-GPU which means they have 2 PCIe x16 ports for GPUs, but I don’t intend to use both of them, maybe only one port after a while. so there will be one unused port at any given time, my concern about this is: Will that second unused port slow down my GPU installed in other port?
Because since there are two ports the total number of PCIe lanes from the CPU is devided between them, so half of them will never be actually used, my GPU would work at only 50% of it’s pottential due to that reason, since insted of getting all 16 lanes each port gets only 8 lanes.
Maybe I am wrong about this nevertheless I am concerned whether or not this theory is true.
BTW: I could use some recomendations about which motherboards to buy, or other components for that matter.
Here is what is important to me for the motherboard to have:
at leats 2xUSB 2.0 on back
at least 2xUSB 3.1 Gen1 anywhere
any number of USB 3.1 Gen2 anywhere
at least one HDMI connector on the back (I coud use two actually (one can be a DisplayPort))
support of achiving 144 HZ from integrated VEGA GPU (some motherboards only
support 60 Hz)
Dual-Chanel memory up to 32 GB or more max. (4 slots)
at least one m2 slot (could use one but is not so important)
any number of SATA connectors
any number of PCI expansion slots
overclocking capabilities are not that important
So here are some data if you have a recomendation feel free to share it.
Thanks in advance
