Trying to keep life in my PC for a little bit longer. New to the whole upgrading thing, so looking for some advice. Here is my current setup, the power supply not sure what make but have listed watts. I am planning to upgrade my machines RAM to 4GB as well, don't know if that makes a difference? 1. Motherboard - Dell model: OF4991 2. Graphic interface -Nvidia FX5200 128MB RAM AGP version 3 8x 3. Memory - dual channel ddr 1024MB 4. CPU - Intel Pentium 4 5. CPU Speed -2.8GHz 6. Power Supply Make/Model - ?? 7. Watt output/Amperage - 250W As for budget well and use....budget for parts is around £50-£60 and its used for FPS and some RTS games, mostly online FPS. Looking to play COD4. Any advice would be gratefully received. Thanks in advance.
