Do I have the right driver?

Back when I built my current PC in June of 2010, I installed Windows XP 32-bit on it. As of May 1, 2011, I upgraded to Windows 7 64-Bit. When doing so i formatted my hard drive to start fresh. Once I downloaded the updates i saw that it automatically downloaded the driver for my ATI 5570. Back when I had Windows XP, I had to install the driver manually and it came with catalyst manager and such. My main concern is that in my programs it says, Microsoft Visual C++ 2008 redistributable x86. Shouldn't it say x64?? Do I need to download something? I don't care about catalyst, I just want to make sure I have the right drivers to optimize my 64-Bit OS.
