I want to get vista, but i dont know much about it. And if I get vista do i have to lose every thing on my hard drive? I noticed how there is a upgrade and a OEM. Does the OEM erase the hard drive and start new? I was looking at newegg and i noticed it was only 94$ is that the real thing because i dont remember it being so cheap. http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=2060350368+1179216458&name=Premium Also does vista sp1 run good or is there any problems still?
