[SOLVED] Building a new rig: Question on PCI Express 3.0 x 16 video card compatibility with new motherboard.

[jimmy328]

I’m building a new rig (every 5 years) and have a question regarding compatibility.
Currently; I have the video card which is the,
“MSI GeForce GTX 1070 8GB GDDR5 PCI Express 3.0 x16 SLI”.
I have not yet used it because the PCI Express 3.0 x 16 slot of my MB has failed. Therefore, I am building a new rig with an Intel Core i-9 proc and an LGA 1200 MB. There are many choices of motherboards that include PCI Express 4.0 x 16 slots or PCI Express 3.0 x 16 slots or a combination of each. I understand the 4.0 x 16 slot is backward compatible, so my current video card would work. So, should I buy a motherboard that includes a 3.0 x 16 slot that matches my video card? Would my current video card work just as well in a 4.0 x 16 slot? I would prefer to buy a MB with all PCI Express 4.0 x 16 because I want the latest technology. Eventually; I will upgrade to a video card that uses the 4.0 x 16 architecture, but currently, they cost too much.
Thank you.

yup. they are backward compatible

If you want the latest technologies as you say, then you should really be getting an LGA1700 motherboard and an Alder lake 12X00k.

Some of us prefer to stay at least 6 months to a year behind on OSs and systems.
Let someone else be the beta testers and once it has matured a bit , then adopt it.
win 11 and 12xxx series still has a while before all of the bugs are worked out and DDR5 is available at reasonable costs.

Thats all well and good but let me clear up some of what you said. The 12000 series processors run just fine on Win10 performance wise. They gain power efficiency on Win11 primarily. There are just as many DDR4 motherboards for LGA1700 as there are DDR5 motherboards and they perform similarly either way. When someone says they want the latest tech I take that to mean the actual latest tech from AMD, Intel, and Nvidia. Respectfully, helper800.
