-- Posted by circa at 7:55 am on July 1, 2008 I currently have a dual 64-bit processor from Intel. It's 2.8GHz. The problem is, I've got the 32-bit version of Windows. Will there be a ridiculous, considerable and noticeable difference if I upgrade the OS, or is there no point in doing so? I don't really expect answers, so this is mostly a thread where I'll ponder the question by myself. mmm. -- Posted by reev at 7:56 am on July 1, 2008 you on vista or xp? I use a 64b version of vista ultimate and it's a huge difference compared to the 32bit -- Posted by scottyrob at 7:57 am on July 1, 2008 The only noticable difference between using any 32 / 64bit OS is the amount of ram it supports 32Bit supports upto 3Gb ram, 64bit supports at least 32Gig It will not noticably effect anything else -- Posted by circa at 8:03 am on July 1, 2008 Quote: from reev at 10:56 am on July 1, 2008 you on vista or xp?

Vista's too much of a burden to learn as of yet, unfortunately. -- Posted by pleaseremove at 8:24 am on July 1, 2008 There is no real speed change between them. All you end up with is more address space so you can have past 4 gig or RAM and video memory combined. -- Posted by Tursi Askari at 9:21 pm on July 1, 2008 Quote: from scottyrob at 2:57 am on July 2, 2008 The only noticable difference between using any 32 / 64bit OS is the amount of ram it supports 32Bit supports upto 3Gb ram, 64bit supports at least 32Gig It will not noticably effect anything else QFT. And unless you are an application whore who likes to have every app on their computer going at once, you won't need more than 3Gb.
