Mother board and graphics card upgrade

Hi there,
I just bought a new computer and I want to upgrade the video card. Do I need to consider the Speed(?) of the motherboard when making this decision? Could my motherboard limit the performance of the video card? I was thinking about buying a radeon hd 4890. Any advice or opinions would be greatly appreciated!

  1. Hello and welcome to the forums :)
    For a single HD 4890 make sure your motherboard has a PCI-E 16x slot with a sufficient PSU,for 2 4890's make sure your motherboard supports CrossFire.
    What are your system specs ?
  2. As Maziar said, tell us what your processor is, as well as the other hardware.

    You may need a more powerful power supply together with the card.

    500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended (600 Watt and four 6-pin connectors for ATI CrossFireX™ technology in dual mode)
  3. Ok thanks guys. My processor is a core 2 quad q8300. My power supply is only 300 watts, so I will need a new one of those. There are 8 gigs of ram (ddr2, but thats all I know about it). I only have one PCI express x16, so I can only run one card. Do you guys think it would be worth upgrading the motherboard to run 2 vid cards? I'm not an ultra-serious gamer, but would one hd4890 be enough to play newer games on fairly high settings, around 1600x900?
  4. For that resolution a single HD 4890 suffices no need to upgrade your motherboard,your CPU and RAM are fine too.
    Only get the new PSU,plug in the new card and enjoy :)
  5. Thanks, I really appreciate the advice!
  6. No problem glad to help :)
