I do not understand what you exactly wants to do. You had given such a long list of your system configuration but not clearly specified your actual issue. Do you want to for a new graphic card upgrade for your Intel 82945G Express Chipset. If yes then you have to first get details about the motherboard specification. It is important to figure the compatibility issue of latest gpu with your board.
