PCI-e Compatibility ( 3.0 GPU whit 1.x MOBO )

[mihalyk2000]

I want to buy a gigabyte windforce r7 260x GPU but I have an old mobo, whitch support only 1.0 ( It's saying only PCI-e 16x ). It will work ? Mobo is: 0a64h ( old one )
I know it will be botlenecked by CPU, but I will buy it for a future build 🙂

Yes it should work, but it will be limited to the bandwidth of 1.0. Granted a 260x is not the fastest GPU so it shouldn't make a big difference...

I seen some places that they are SOME GPU-s which aren't compatible whit PCI 1.x, and on recommended it's PCI-e 2.0. This is just a fake info, and I can use PCI-e 3.0 GPU on PCI-e 1.0 (x16) ?

It will work, but remember what others told you in your previous thread. Some games will simply not work because your CPU will not meet minimum hardware specs.

It's not fake info, they do recommend 2.0 or greater because most modern GPUs are bandwidth limited in PCIe 1.0. But like I said, a 260x isn't a blazing fast GPU and your not going to be doing any high def gaming with it so you likely won't even notice a difference. In general, PCIe is backwards compatible.

Okkey, thanks for replys! I will buy that GPU, I hope that everything will be fine 🙂 I read a lot of forums about this, and I was 75% sure, cuz there were some places where they said that it will not work... Now, somehow I feel more safely :3 Thanks for everything. PS: I know that CPU is bottlenecking, but I will change the pc in some years.
