Graphics card compatibility

Hi, I currently have a Dell XPS 8300 desktop pc with a 2nd gen Intel i5-2310 processor and associated motherboard along with a Radeon HD 6450 graphics card. I want to replace the card with either the new EVGA Geforce GT 640 2GB card or Radeon HD 7770 1GB card to enable me to run three monitors at once which I am reliably told these cards can do. Not for gaming though.
Is my XPS hardware capable of running one of these cards for three monitor purposes?
Or, do I need a processor and motherboard upgrade also?
Thanks

  1. According to AMD the 6450 you have supports 3 monitors see http://www.amd.com/us/products/desktop/graphics/amd-radeon-hd-6000/hd-6450/pages/amd-radeon-hd-6450-overview.aspx#2
    "Native support for up to 3 simultaneous displays"
  2. Sorry, should of said I want to upgrade the existing 6450 for better quality.
  3. The 8300 specs say you have a 460w power supply, so either of those cards should be fine. My worry would be the room for a 2 slot gpu. If you look in your case, is there a decent amount of space below your graphics card right now? If so, either card would be fine, and for your use I would pick whichever card is less expensive. If not, your going to have to rethink your choice of card.
  4. Looking at the rear of the case, there are 3 slots free under the card, so presumably space available but I'll remove the case to make sure. Cheers
  5. You should be good to go then. Looking around, It appears there aren't many places, if any, to buy a gtx 640, so that leaves the 7770.

    What connectors (hdmi, dvi, display port) are you using for your monitors?
  6. Intending to use hdmi for a tv and dvi's for my two monitors.
  7. I'd recommend this card then.

    Don't let the reviews throw you off, I've seen many asus cards and they all were great. Just make sure to keep your drivers up to date too. :)
  8. Yes thats the HD 7770 version I was thinking of cheers.
