GTX 780: PCI Express x16 3.0

post #1 of 3
Thread Starter 
My motherboard says that I have a PCI Express x16 slot and that all of my PCI Express slots are 2.0. Are there any reasons for upgrading my motherboard to PCI Express 3.0 to get the most out of a GTX 780 and will I also need to upgrade my CPU if I want 3.0 speeds?

Thanks,

Well your board supports pci-E 3.0:

You'll need an IVY Bridge cpu to get pci-E 3.0 itself.

Might gain 1 - 2% more performance going to pci-E 3.0

this^ I have the same board on my wifes rig and it does support PCIe 3.0 but as said you need an ivy CPU for it to work. i dont think i would bother to upgrade the CPU as PCIe 2.0 will work fine still.

If you decide to upgrade to ivy, make sure you update to the very latest BIOS as it is the only one that will work with Ivy on that board. On the other hand you need the UEFI BIOS on this particular GB board to allow overclocking since the latest hybrid EFI BIOS locks the multi of the CPU. I didnt bother with the UEFI BIOS since my wife doesnt care and i hear it is not that stable. You might be able to get the latest Hybrid EFI BIOS HEX edited to unlock the multi if you can. Anyway point being you are better off with a sandy with that mobo.
