I am about to purchase a 2010 quad 2.8. I have 2 easy questions: 1) I plan to later upgrade this to a six core, can I buy the memory PC-10600 memory and use it on the 2.8ghz that way I am ready for the 6 core? 2) What size SSD should I get for boot and applications? Is 60Gigs enough? I will be running Lightroom 3 and CS5 on this machine the majority of the time.
