Got an older Dimension 4550. Has only 512 of RAM. Currently running an older 4xAGP card (the VISIONTEK XTASY RADEON 9100 128Mb - VTK 9100128AGP). Runs fine but I need a dual DVI card and (if possible) one that would be Vista Aero compatible. I know I'd need to bump the RAM up to a gig which might not be practical $ wise with a multiple year old PC, but anyway... PC is a biz PC with email and surfing. No heavy AV or the like usage at all. No gaming either Suggestions? Thanks! EDIT: DAMN! First post and I pooch the spelling of the headline! puke: EDIT #2: Checking the specs of the system, only has a 250 watt power supply but has virtually nothing inside the case that isn't stock other than a NIC in addition to the onboard one.
