Flash in Vista 64 bit HP and Radeon HD 6670

Hi I installed Vista 64 bit because major infrigements on using Starcraft 2. It was just too slow on 32 bit so I changed the performance. Unfortunately I cannot use hardware accelerated browsing in 62 bit vista. Everything is very, very slow on ie 64 and mozilla 10 32bit.
Does anyone know about this?

Did you upgrade all the hardware to their 64 bit drivers after installing Vista 64 bit?

Man I was biased. The system worked from beginning.

What does that mean?
