Hey guys, this is my first post here. It's nice to meet all of you! I'm thinking about getting a 17-inch MacBook Pro. I'll be putting a 2.3GHz Quad-core Intel Core i7 Processor in the laptop, and I was wondering about what RAM I should get. I'm thinking about getting 8GB of DDR3 SDRAM, but I'm having a problem with one thing. What does the MHz mean? When I customize the MacBook Pro on Apple.com it only give me the option of getting 1333 MHz. Is that the highest that MacBook Pros support? Can I get a higher MHz? Thank you!
