Have to concur with GD on this, I built my PC no less then 2 yrs ago, up to 3 yrs ago, and it is still a strong machine, I don't think there is yet a game or program(PC Version, I am well aware that tiger will not run, nor any other mac program
) that will not run on it. Of course I bought the best components available at the time, and I don't forsee having to replace it anytime in the next couple years, in fact I will probably use it in one way or another for another 8 to 10 years. One of my first computers I built is still going strong running freebsd and functioning as a file server (did it because I can). I will probably eventually transition to a mac, but that is purely for photoshopping reasons (considering getting a few mac mini's to spread around my place; for studio, and a few photoshop and print stations).
