I have an IBM Aptiva 2170 which is getting really outdated. I think my weakest link is that I still have the original 64 meg of memory, and am cosidering spending the $70 to upgrade to 256. (At some point in the past I upgraded to a new hard drive and CD-RW.) I am also wondering if I would be better off buying a new mother board with a speedy new processor. I am worried about everything else being compatible though. I am not looking for blazing speed, but would like to improve what I have significantly. Does anyone have suggestions on how to procede?
