I am in need of a cumputer upgrage or new computer all together and I am just looking for some help.I see 2.4 duo core stuff, 2.4 xeon, etc... What will be the best bang for my dollar. In my head, I have a hard time going to a 2.4 xeon when I am currently running a 3.2 Pent 4. Would a xeon be faster then the Pent 4? Does SolidWorks use the duo core efficiently? Or am I just better off adding a sizeable chunk of RAM to my current 3.2 Pent 4?
