What upgrade is more cost effective: RAM or Chip speed/model?
I need to buy a new 15" MacBook Pro (standard screen, no retina; hard drive, no SSD). I want to upgrade from a couple of the in-store configurations, so I know I have to uze the online store.
My *most* memory-intensive work is some occasional production (hobby) in Logic Pro, which does slog down sometimes on my existing '08 MBP with a 2.4 GHz Intel Core 2 Duo, running 10.6.8 Snow Leopard. And my 4GB RAM do get a bit constipated if I'm running Photoshop Elements with two or three other minor apps open. I don't do any games, and very little video. The in-store standard is 2.3GHz Quad-core Intel Core i7, NVIDIA GeForce GT 650M with 512MB GDDR5 memory. For $200 I'll get a 2.6GHz Quad-core Intel Core i7, NVIDIA GeForce GT 650M with 1GB GDDR5 memory. (What's GDDR5?)
I'm comfortable enough paying an extra $100 to double the standard 4GB RAM to 8GB. And I'm fine with another $100 for the 1TB internal @ 5400rpm, as I have about 700GB data and I =want= to keep it all internal and physically local (plus external bootable clones in rotation). Given that the standard chip is only .1GHz less, is it worth $200 to hop up to the 2.6GHz? (It's another $250 for 2.7GHz—forget that.) I'll appreciate any input on juggling which variables matter more. Thanks.
