I got a "Radeon HD 4550" but Windows reads "Radeon HD 4350". On the first run Windows 32 bits reads 4550 but when I changed to 64 bits it reads 4350. Am I ripped off by Bestbuy? In the package it comes with a low profile bracklet but the ports are not corresponding to the ports on the card. I brought this on "Black Friday" 2 years ago. Is the specs required?
