  1. It should be fine. PCI-E 2.0 cards work on PCI-E 1.0 boards, and PCI-E 1.0 has plenty of bandwidth for every card out there so far.

    What kind of power supply do you have? You need to check that it's powerful enough.
  2. Hi rofllol100 and welcome to the forum.
    As aevm says it will work yust fine :)
  3. I was about to ask the same! :)

    I have an A8N-E with PCI-E 1.0 and want to add a 8800gt 2.0, is aevm, the same for every card in the market? or your comment was just for the HD3870?

    I have an Antec TPII 480w, i hope is enough!

    Edit: Sorry about this, i saw the answer in a different post. (i should write 1000 times, "read before ask")
