I used to have a dual boot of Vista Ultimate x64 and Xp SP3. As soon as I replaced Vista with Win7 Ultimate x64, I knew that finally I would have an OS that could handle the High Def side of my computing as well as the basics such as decent gaming. Vista was a total resource hog on my laptop as well and Win7 is a complete improvment on that front. I am getting rid of XP and Vista and migrating everything into Win7 Ultimate. I happily wiped vista and in fact i am installing the windows98 UBCD 2008 on that same drive so that i can natively run all of my ancient dos games on it. Who would have thought that win98 could run on a dual core or quad core with 8gbs of ram? I also managed to get flash 10 and directx 10 on win98 too.. Thanks to the people on msfn.org!
