In my opinion, windows Vista is horrible. First of all, it uses too much RAM, which overall slows down your speed. Is all those fancy unnecessary clumped objects needed? Also there is basically no game support, most games don't even function. And worst of all, theres that decline in fps. In first person shooters, you need fps. I found out that the hard way. I hate vista, i reformatted and I will never use it again.
