Hello there, I am about to put an order in with OWC to purchase some upgrades for my quad-core Mac Pro 4.1. 8GB RAM 1TB WD Caviar Black 5870 Ati Radeon Basically if I buy the 5870 with the HD and RAM, I save about NZD$200 as opposed to if I got the 5870 through the Apple New Zealand store. My question is will I get spiked in customs with my order? Also in the event of failure, will I be able to get support in New Zealand for the 5870 with Apple? Thanks heaps for any responses!
