GPU running in PCIe 3.0 x8

Hi guys,

kinda ran into an unexpected issue. I'm building a budget gaming PC for a friend and this is what I ended with:

  • Motherboard: MSI B450 GAMING PLUS
  • CPU: AMD Ryzen 3 2200G
  • RAM: 2x8GB ADATA GAMMIX 3000MHz
  • SSD: Samsung 860 EVO SATAIII 250GB
  • HDD: WD Blue 1TB 7200rpm
  • GPU: Sapphire Radeon RX 570 NITRO+ 4GB
  • PSU: EVGA 500B
  • Case: Fractal Design Focus G

Everything is working and looks like a fine gaming PC for me, but I ran something that pisses me off. When I changed something in BIOS, I noticed that my PCIe slot with graphics card is running only at 8x instead of full 16x like everywhere else. After looking to manuals and spec sheets, I found this on manufacturer's website:

Quote
  • 1 x PCIe 3.0 x16 slot (PCI_E1)
    • Supports x16 speed with AMD® Ryzen™ 1st and 2nd Generation processors
    • Supports x8 speed with AMD® Ryzen™ with Radeon Vega Graphics processors
    • Supports x4 speed with AMD® Athlon™ with Radeon™ Vega Graphics Processors
  • 1 x PCIe 2.0 x16 slot (PCI_E4, supports x4 mode)1
  • 4 x PCIe 2.0 x1 slots1

My question is: Will x8 speed on my PCIe limit the GPU so much I will not be able to play online games such as Fortnite, League of Legends, World of Tanks etc. at reasonable FPS ?

 

I know Ryzen 5 2600 will be a sweet spot but budgets are budgets ... I can try to swap it for something like Ryzen 3 1200 or something along those line but that would mean a better cooler for OC which means more money.

The difference between x16 and x8 on a GPU is a few fps... at most. 

 

You'll be fine. Go have fun.

Phew, you saved my bacon, thank you kind sir! :)

I was worried I screwed up heavily with this selection ... Today I plan to test it so we will see.
