I am going to build my next pc, but want to be ready to take advantage of all the features of the best version of windows vista. I don't have any preferences as to amd or intel, nvidia or ati. Should I start buying components now, or wait for vista to come closer to coming out. I don't want to get a gateway, dell, or hp prebuilt unless someone convinces me it is the best way to go. Budget is $2500 or so USD. Only keeping current my current mouse, Plextor CD/DVD burner.
