Hey all, I could use your help. I've been telling my gf for MONTHS now that to speed up her slightly-laggy MBP, she should upgrade her RAM from 512 MB. she finally bit the bullet and upgraded to 2 GBs. Obviously, she expected an extremely snappy result; however, she tells me that the computer feels exactly the same! RAM tests all come back positive... what's the deal? Maybe the question I'm asking is; exactly WHAT tasks does RAM supposedly speed up? Where should she look for a speed increase? Thanks!
