I will be getting one today, but I wanted some advice from my fellow MR. As always there seems to be a perfect bang for your buck model and I wanted to know what you guys thought. I am upgrading from a late 2009 27" 2.8 ghz i7. I really wanted the new i7 but I don't know if I can wait. Can you guys give me some advice? How does the new i5 Compare? Is it worth it to upgrade to i7 and upgrade the graphics? What kind of changes will i see. Also do they sell these in store today?
