Help needed please I have a powermac Dual 2GHz powerpc G5, memory 3.5 GB DDR2 SDRAM, Running Leopard 10.5.8. I want to upgrade the graphics card which is a `NVIDIA GeForce 6600 LE` Chipset Model: GeForce 6600LE Type: Display Bus: PCIe Slot: SLOT-1 PCIe Lane Width: x16 VRAM (Total): 128 MB Vendor: NVIDIA (0x10de) Device ID: 0x0142 Revision ID: 0x00a4 ROM Revision: 2149 So I bought one off ebay a Nvidia GeForce 7800Gt 256MB PCIe. Which I thought was an upgrade option for this model. Simple enough to install but when booted up my monitor screen shows a box saying `no video input` Have I bought the wrong card, can I get this card to work in my G5? Regards Rob.
