I have a HP Pavilion with AMD Athlon 64 X@ 4800+ processor, Raidmax Volcano 630W PSU, ECS Nettle motherboard and Phoenix Technologies BIOS version 5.09, 4096 MB DDR2 memory, and a failed NVIDIA GeForce 6150 E nForce 430 graphics card. I had been using the graphics card to run two analog displays. What kind of card should I get to replace it? Is there a better card to buy; is this same card even available (it was adequate for what I do)? Thanks!
