I have a low end desktop (lenovo k300-5316). The mobo has no option for oc. I am considering getting a new cpu. However, I am tempted to just wait until I have enough money to build my own rig (which would be in a few years). In the meantime, I was wondering if it would be worth the money to upgrade my cpu. If I do upgrade should I do a dual or quad core?
It all depends on what quad you are looking at needs to be a Q8400 at minimum to get noticeable benefit from the upgrade. 2.4GHz or slower quads will perform some tasks a lot slower than a 3.2 GHz Dual core.
