I think I know the answer to this, but it's nice to get the opinions of others. My PC currently has an Athlon XP 1700 (1.46Ghz) processor & 256MB oF PC2100 DDR RAM. I use it for surfing the net, running office apps, playing CDs & DVDs, and the basic manipulating of audio (wav & mp3) & video (jpg, bmp, etc.). Should I upgrade my PC? If so, to what extent? Thanks in advance.
