You've just made my day a whole lot better... lol I have been waiting and waiting for Halo 2 to come out for PC. (I don't have an Xbox) But when I saw it was for Vista I was HEARTBROKEN. Thanks for the ENCOURAGEMENT Carbon Dudeoxide! Lol, no problem. I just can't wait for it now that I know it's coming out for XP.You and me both. I googled "Halo 2 for XP" and found a website that claims that if you buy the game from them they will send you the XP patch along with it... www.fallingleafsystems.com They said it was supposed to be ready sometime in July. Not exactly sure when though. I'm excited!! Got Vista with my new PC..... I wanted to go SLI when I upgraded....runs newer games well and most online games... I hear that Vista has problems with SLI....I hope not!!! I run Flight Sim alot with no problems....Currently I don't think it's worth it, since there aren't too many ground-breaking exclusive games at the time. Besides, most of the UPCOMING games are compatible with DirectX9, and can still run smoothly given the right HARDWARE. Maybe in a couple of months or so it'll be worth it, and we'll get to see the full power of DirectX10, but right now, I'm liking my "old" rig I built BACK in '05.
