Question Upgrading GPU, do I need to worry about PCIe and lanes?

[bcemail]

Got some great help recently as I try to do some budget upgrades on my PC. I have an RX 580 8GB and I'll be upgrading my CPU to a 5600X or 5700X. My mobo has a PCIe16 slot running at 3.0. I just read something about using a GPU with PCIe x 8 in a x16 slot and that it might weaken performance. Should I be worried about this?

I have been looking at cards like the 6600XT and 6650XT which are listed as PCIe 4.0 x 8. Is it ever better to go with an older card that has x16? Am I over thinking things here, especially since I'm not building a cutting edge system?

Thanks!

Please mention the make and model of your motherboard and processor.

Sorry, Mobo is a gigabyte ga-ab350m-ds3h. My current CPU is a Ryzen 7 1700x but that will be changed to 5 5600x or 7 5700x

Thanks for that! Sounds like there can be some performance decreases but not a deal breaker. Maybe I'll try and focus on 16 lane cards. Lots of variables so each time I search I seem to decide something different about what's the best value!

Almost no difference in 3.0 and 4.0 using either card listed.
