Primary use of PC: Gaming and Video Authoring I'm real sick of how vista scans my hard drive constantly eating up my system resources when there is no need to be scanning it at all since thats what my a/v is for and the fact that vista is taking up double the space of a program requirement. Every file we install on vista has a duplicate install in a virtual folder under roaming inside users directory. When a gamer installs one of their favorite games on vista, vista makes a full duplicate copy in the roaming folder for no reason than to waste good useable hard drive space. I have been seriously considering going back to XP 32 Bit with SP3, but if I do then I lose the use of 4GB of RAM when using games and video authoring software. So I need your help in deciding what is best. I have been trying to get a game called GRID to run under vista for two days and while it does play it crashes constantly and the nvidia driver stops responding. I have also noticed problems when video authoring and other system instabilities thanks to whatever new patch microsoft released. Whatever they released fixed one thing, but broke alot more stuff. Now for the poll: If your pc was primarily for gaming and video authoring which OS would you use? Keep in mind going from vista 64 to xp 32 you lose 4GB ram usage.
