Pci-e 3.0 and pci-e 2.0 question

quick question on compatibility... I have a mobo with a PCI-e 2.0 x16 slot, and I just picked up the new Nvidea 680 using the new PCI-e 3.0 standard. In my haste to get the card I didn't check the interface and missed that it used 3.0 While I know the 3.0 cards will work in the 2.0 slots, will i see a large reduction in performance? anything I can do to limit that short of buying a new Mobo?

my motherboard:
GIGABYTE GA-Z68X-UD3H-B3 LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard

My vid card:
EVGA 02G-P4-2682-KR GeForce GTX 680 2GB 256-bit GDDR5 PCI Express 3.0 x16 HDCP Ready SLI Support Video Card

  1. thank you... like a noob I continued to search and I came to the same conclusion a few seconds ago...

    Different question now... I built a new rig and had a gtx 580 in there before i was able to get the 680, but I neglected to remove the driver for the 580 before getting rid of the card. will I encounter any problems when I install the 680? Can I boot like normal off the 580 drivers, then uninstall those drivers, then install the new ones? I would think the computer would just use default drivers until I remove the 580 ones and install the 680 right?

    Yep, you can remove your old drivers before installing your new ones, if thats what your asking. It is even recommended to do so. Also as gary1 said, you will not see any difference, unless you plan on running a large SLI set-up, then you may see a small difference.

    Hope this helps
