Hi is it worth it to keep my pc...it's a Compaq 475mhz with 10gig HD and 64 mb ram. I installed a 2nd 20gig HD and another 64mb ram and a new CD-RW and have no problems...would a faster cpu make any difference and would there be a compatability problem with a faster processer? How about more memory...thanx for the imput...... <IMG SRC="smilies/cool.gif" border="0">
