No its not at all. At home I have a e6300 w/ 2 gigs of RAM and a 9800 pro (256 meg version) in it. It is a secondary system. Something I use to play around with and load OSes on. I have it booting Linux, Vista business, and XP. These more than meet the minimum spec requirements for Vista. The requirements can be found
here.
When I do side by side comparisons of XP versus Vista I get no performance increase at all. Things run pretty much about the same. I use it on the basic level. Ripping music, burning CDs, surfing the web, opening office documents, and the XP machine performs the same or in some cases faster due to buggy software.
However, I digress, I am done trying to debate anything with some 14 year olds. It is pointless. So I am done with this thread completely, and if this keeps up the forum as well.
