I bought a HP 6599ee with vista home premium and I must say after getting used to it and adding all the necesary updates, it really does blow XP out of the water. Yes it does have a few teething problems but that is to be expected for a fairly new o/s. Just so you get the idea, I have been playing Supreme Commander on a notebook with all settings on max, that includes 8*AA and the game is running smoothly. Oddly enough I read an article about how vista framrates increase with AA on, so I tested it out and it really is true. I have not tweaked any settings in my vista and norton is running and I still get smooth performance. I am truly amazed. Just thought I needed to pass on the good word. In the future this O/S will truly fire on all cylinders. If I run into any problems I wil be sure to update this post. Be sure to download vista update KB940105. It made quite a difference to my games performance. If anyone has any problems with this update please feel ffree to post here. thanx Grant
