Since going with the Mac Pro about two years ago, I've enjoyed lots of PC games. I've installed a larger Nvidia graphics card and have enjoyed its improved performance over the stock card. I also have a copy of Windows Vista 64 bit sitting on my shelf. However I ask myself why? Why do gamers even need Vista or Windows 7 for that matter? Most games are still written for Direct X 9.0c and Windows XP. I'm sure that will change over time, but very few games are coded for Direct X 10 with the advent of Vista. Does anyone really care about using Vista or 7 when it comes to gaming on the Mac?
