Im playing to buy it around christmas time and i had questions on which mobo to buy. Im planning on getting one of the new dual core penryns that come out, the 3 ghz one most likely. I dont know which mobo to buy though. I currently have a pc from dell, that ive modified almost everything on it. save for the harddrive. So i am just going to replace the mobo and cpu on it. The only problem i have is that the mobo i have now i think is a micro-atx. i was wondering if i would need a new case if i got a new motherboard. i have an air cooled machine and i might plan on light overclocking. i have DDR2 PC4300 1.5 gb of ram as well. i dont know if i would need new ram as well because mine right now is somewhat slow. thanks for the help.
