As you can see I have a 1.8ghz P4 CPU, but have just heard that a 3ghz P4 is now out! When I feel the need, will I be able to upgrade my processor and if so can I upgrade to the new 3ghz P4's?? A friend said I cant upgrade my processor because it has a 400mhz bus (what ever that means!?) and that they don't make these no more!!! Also I am running windows XP home and it can be quite slow for a new computer. Would upgrading my graphics card have much of an effect? If so, which card is recommended for my computer? I will be forever grateful if anyone can help me. I have included a MSinfo document, if that helps. Any recommendations on improving my computer will be gratefully accepted. Thank-you.
