Hello all. I am new to this site and have minimal computer experience. I love to tinker with circutry tho . I recently bought a laptop ( Toshiba Satellite L305-S5955 ) and i have come to the conclusion that i need a better cpu. I have some questions after reading about other processors tho.... mine has a FBS of 800... if the processor i buy is larger, will it still be compatible with my mother board? Alot of the others i have read about seem to take less power, ergo creating less heat...... so will the cpu fan i currently have still be sufficient? Will a Dual core be larger than my current one? I have decent skill in soldering small objects w/o frying surrounding circutry, but not sure if replaceing cpu is a plug and play deal or soldering deal. Any suggestions as to what a decent cpu i can upgrade to would be very appreciated aswell as the process needed to do the job myself. Thank you to all who read/post
