Well I have a little bit of money and I want to upgrade my emachines T3958. Here are the specs, http://reviews.cnet.com/EMachines_T3958_Celeron_D_340_2_93_GHz/4507-3118_7-31315075.html I will be upgrading my video card, ram, new fan and heat sink for the processor and a bigger case fan. I am curious if I am able to OC anything. I will be adding 1g of ram to the system. I am very new at overclocking. thank you for any help.
