I have an early 2009 MBP 2.5ghz i5 with 4g of RAM. It gets overloaded when I'm using FCPX. Would adding RAM and a FW800 drive improve things dramatically, or should I pass this laptop down to my wife and get something with a i7 chip and Thunderbolt? If buying newer, there's a 2011 i7 2.4 refurb. Think this would get me by? I would probably still add RAM to that it looks like, as 4g is all it comes with.
