I'm checking up on various components to upgrade my PC. At present it's a SLOOOOW P4 1.7CPU witj 512MB Ram running Win XP SP2. I've been told that upgrading to a 2.8GHZ or gigher CPU will improve the situation. I'm unable to afford the more expensive Intel Pentium 4 2.8CPU, but can afford the Intel Celeron 2.8Ghz CPU. However, some "experts" have told me that the Intel Celeron 2.8 is hardly any better than the 3 year old P4 1.7 CPU I currently have, and I'm wasting my money and will see NO speed results? Is this true, why is the Celeron so much cheaper (Here in South Africa a Celeron 2.8CPU runs R800, whereas the P4 2.8 is R1400) Is the Celeron an inferior processor? BTW, my MB is an ASRock GePro M2 Thanks.
