Hi everyone, I want to buy the new 15" MacBook Pro, likely the base $2400 build but I have some questions first. First, when do other sellers start selling them? I'm talking about MacMall, Amazon, B&H, etc. I'd like to order my laptop from one of them to avoid paying a ridiculously high sales tax. And when is the best time to buy with the highest discounts? Anytime from now to new year. Second, where can I find benchmarks between the CPUs available in the customization options. I'd really like to know if it's worth paying the extra $300 for the bump from 2.6GHz to 2.9GHz, or if I should go ahead and double that and bump it up to $600 for 2.9GHz, double storage (512GB), and Radeon Pro 460 instead of the 450. I'd also like to know the benchmarks for their Radeon Pro 450, 455, and 460. Either customized it a bit with upgrades or go with their base option. Any help on this is greatly appreciated as it will help me decide what to get. Finally, did apple start selling USB-C adapters and do you have any recommendations on that? Many thanks for all your help!
