I'm looking to get a AGP mid-range graphics card to last my PC another year or so before I upgrade to a PCI one. My power supply is relatively weak so I can't get into anything really good but these two cards, XFX GeForce 7600GT 256MB and the SAPPHIRE Radeon X1650PRO 256MB , were the two recommended to me. I currently have an Radeon 9600 in the system with an Asus A7N8X v2.0 Deluxe motherboard. Would I have problems switching to the 7600GT? I have already checked the power and memory requirements, is there anything else I need to be sure of before buying either of them?
