1. Motherboard - ASRock P4i65G (1 Socket 478) 2. Graphic Interface - AGP 8x 3. Memory - 512MB 4. CPU - P4 5. CPU Speed - 2.8 Ghz 6. Power Supply Make/Model - ISO/ISO-450PP 4S (it`s the model No. on the Power Supply, don`t know if it helps) 7. Watt output/Amperage - +12V/16.0A although the power supply itself says max. 350W, the store where I got my computer from states max. 300W. I want to have some more power to my machine so I thought of buying a new graphics card. Since I have AGP, I thought of 256MB Club 3D 7600GT AGP (maybe even x1950 pro AGP, but I guess it`s too much). At the moment, I have Leadtek WinFast A310, I believe it was nVidia 5100 or something. I could, however, afford a new PCI-E motherboard and PCI-E graphics card also, but I can`t change my 478 socket CPU. So, I`m asking, is it possible, is it worth buying and which option would be best and will it run games like Neverwinter Nights 2? Any help would be appreciated.
