Hi there, im from brazil and im going to visit new york for 9 days in september. I'm going to buy a full computer there but theres not a lot of big stores that i know. I just know Bestbuy, BH and JR. The problem is that i want to buy really good components like Radeon 6990 or GTX 590. I cant buy on newegg or other shipping stores bcause im afraid of be charged and leave the country before the package arrives. Theres any other phisycal stores that u guys know?
