As a comparison; I have both XP Pro x64 and Vista Ultimate x64 with both having 8 gb's ram. Only difference is Vista system has a Quad Core Extreme cpu with water cooling and the XP has a Core 2 Quad with a V8 heatsink cooler. But as it goes the XP boots faster than Vista does. Also the only other difference is my graphics... which on the XP it is only one gpu and on the vista it is two gpu's. Thus graphic performances can not be compared much. But they both run the same games and only difference is the frame rates and over all wieght of how it is visualized. Same monitor on both and my two kids would have nothing less...
One hates Vista - the other hates XP. So they get what they want and it works the way they want for each others own preferences.
Thus I could care at all if it was faster or slower. Long as the kids play their games and are happy with the OS they choose. Then it's OK.
Xp only uses 2gb ram maximum so you are comparing Vista running 4 gb vs XP running 2 gb. Vista on 2 gb is nowheres near as fast as XP so the blanket statement is valid.
So I some what agree with you NT! And where you been there big guy? Have not seen you around since the GUI champs. Whatever - glad to see your crunching key boards again and hey - working on anything new there?
