this question comes from my repeated freezing up in bf2, and someones solution i need to update my drivers. i have a sapphire x850xt pci express. now, it came with two discs, a catalyst 5.3 disc which i used when setting up my comp, and a redline tweak verserion 2.3 which i didnt use. on the ati site i saw that there is now a catalyst 5.7. now my question is whether i need the redline software, or the new catalyst. and if its the 5.7 catalyst, do i need to uninstall the old drivers or will running the exe auto update them to 5.7. thank you
