Not by much or at all since a PCIe 2.0 x16 is very close to a 3.0 x8. Very few GPU's have reduced performance in real-world scenarios in this regard.

Hello everyone. I have an older motherboard and on this motherboard the only slot available for a gpu is a PCI-E 2x16. Will this bottleneck a gpu designed for a 3x16 slot and if so how much? The use of this computer would be various kinds of animation and casual gaming.

 

Thanks for the help

wont be bottlenecked a noticable amount if any

I spent $2500 on building my PC and all i do with it is play no games atm & watch anime at 1080p(finally) watch YT and write essays...  nothing, it just sits there collecting dust...

Builds:

"Here is some advice that might have gotten lost somewhere along the way in your life. 

 

#1. Treat others as you would like to be treated.

#2. It's best to keep your mouth shut; and appear to be stupid, rather than open it and remove all doubt.

#3. There is nothing "wrong" with being wrong. Learning from a mistake can be more valuable than not making one in the first place.

 

Follow these simple rules in life, and I promise you, things magically get easier. " - MageTank 31-10-2016

If you need some evidence to show that GPUs don't need a lot of PCIe lanes:
