I just received the above card. I bought it from welovemacs.com, but it did not come with any software, CD or drivers, nor installation instructions. I have a Dell 20" wide screen and a new AOC 19" monitor - both hooked up and both working, and both will pivot. I was told by Apple I needed the new card in order to use the pivot function of either monitor. My computer is the G5 tower single processor, 1.8MHz unit with 1.25 GB DDR SDRAM. According to my "About This Mac" screen, my existing graphics card is: GeForce FX 5200: Chipset Model: GeForce FX 5200 Type: Display Bus: AGP Slot: AGP VRAM (Total): 64 MB Vendor: nVIDIA (0x10de) Device ID: 0x0321 Revision ID: 0x00b1 ROM Revision: 2060 So, do I install it as an "additional" card in one of the PCI slots, or "in place" of the existing card? Also, do I need to download drivers from ATI, the mfg? Thanks in advance from anyone who can help.
