Hello everyone!

I own an AMD a10 5800k processor, and have been looking for motherboards for it. I've found some, and they seem pretty good, but one thing is not clear for me.

For now, the choice is between ASUS A88X-PRO and GIGABYTE GA-F2A88X-D3HP

I've read the specifications, and it says that (quote) "To support PCI Express 3.0, you must install an FM2+ APU". So as I understand, with the APU I have (which has FM2 connector) I won't be able to install a graphics card like RX 470 or any other that runs on PCI-e 3.0?
 
Solution
I'm not the best AMD guy, but even if you cannot support Gen 3.0, it will drop down to x8 lanes for the graphic cards. So you can still use it. However, there may be some bottle neck.

It simply means that the graphic card you install with FM2 CPU will work in PCI-e 2.0 mode.

Depending on the setup you may or may not get a performance hit at all.

I had the same issue when I was on i7 sandybridge as it is also limited to pci-e 2.0 but I used a gtx680 and gtx970 on it without having too much performance drop.

Perhaps you do not need to invest in a new CPU.

Well, the processor will probably bottleneck GPU anyways :D so I guess I won't notice it running on PCI-e 2.0.. Or will I.. :D

Anyway, I'm planning to upgrade everything some day (exept GPU if I get like RX 480) but that might be not soon. Hopefully AMD's ZEN technology will reduce the price of Intel processors.

And what motherboard should I get? I don't have much choice in my place (another company is ASRock, but I don't trust them very much, as I don't know anything about them). But between that Gigabyte and ASUS one? Which is better?
