The system specs are out there to run the new os. The problem is that the specs keep rising depending on the version and what you want it to do. Video card is the newest to get the full experiance of the 3D effects and more. The sad thing is there is no release of these so called cards til the end of this year. For the basic system just a 64 mb video card and a minimum of 512 DDR is required besides that as long as it is a pentium 4 3.0 your good to go. Gaming machine will be much more of a complete overhall which I am doing.
