I'm encountering a problem when thinking about the OS I want to install on the computer I am building for gaming. The computer usage is going to be restricted to playing games and watching videos. After purchasing the new BFG Tech nVidia 6800 GT OC I am finding my pockets a little light to be spending nearly another $100 on just a copy of Windows XP Home Edition. My question is this: Should I install Linux on my new computer, or will new games not be made to comply with Linux? My first instinct is that newer games including Farcry, Doom 3, Halo 2, and Half-Life 2 would be made for Linux supported systems. But after a recent conversation with a friend of mine, I was informed that this would not be the case since Microsoft is paying these companies to make them incompatible with Linux. I've never used Linux to know how it works, but another friend of mine has a free copy of it that he will let me use, I just don't know if its what I want on my system if it will not be compatible with upcoming games. Also, my backup plan is to install Windows XP Home Edition from another friend's burned .ifo files. He assures me that the .ifo files are all I will need to install Windows XP, but never having done that I can't feel completely comfortable with that method. Essentially, there are two questions here, the one regarding Linux and its compatibility with games fostered by innovation in the gaming industry, and the latter, whether the .ifo files are all I need along with a cd key to install Windows XP? Thanks for taking your time to read this, and I look forward to hearing some of your ideas.
