I am finding my old Macbook is having trouble running Final Cut Express 4 quickly and efficiently(ie long render times). This is a lack of RAM issue, correct? My 2008 Macbook is a 2.4GHz Core2Duo with 2GB(1 and 1 Apple factory config) of 667Mhz DDR2 SDRAM. I perused OWC.com and see I can get a 2 and 4 config for about $130. Is upgrading to 6GB overkill for editing? Also, what happens to the information stored on the 2GB of RAM; /how/why /should/can I get that info onto these new chips? These may be novice questions, but Ive never thought to install new RAM for editing(Im a college film student looking to get the best for what I can afford).
