HP PAVILION ELITE M9510F

Hello, Just am wondering what you guys think of this puter in general, and with regards to how I would like to use it, if I do get it, would be gaming, and well games like Flight Sims specifically, X-Plane 9, and even Call of Duty type games and so on.. I know abit more about puters, but I'm so used to macs, and this will be if I do decide on it, my 1st PC... Im just not sure about Vista on it tho.. Thought about using Linux on it as well, specifically, Ubuntu Linux.. but am wary on that cause of driver issues and so on, not so easy to find info for this puter specifically... so what do ya guys think? Link is also provided cause this is most like where I'll get it from cause of price.
