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?
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.
