Windows Vista 64 bit - why do I need it?

I understand that the 64 bit version of Vista will allow the system to make full use of 4GB of RAM compared to 32 bit, but I have heard a lot about compatibility issues.

How many programs out there really require a 64 bit OS? Are 32 bit programs compatible? Will most standard peripheral devices (external hard drives, printers, cameras, etc.) work with 64 bit?

It seems that the market is pushing 64 bit before it's time. I don't want to buy a 64 bit machine and have to replace my current accessories.

Thanks!

 

If you have 64bit hardware, i.e. processor, MoBo, GPU then you are ok to run a 64bit OS. Ive been running Ultimate 64 for about 3 months now and have NEVER encountered a compatibility issues. I've run Photoshop CS2, Quark 7.0, and countless games on here without any hiccups. The nice thing about Vista 64bit is that you can run any 32bit program in it. Vista does this through emulation. As far as peripherals being compatible, then don't worry about it cuz nearly all devices now have a 64bit driver available. The best thing you can do before taking the leap in 64bit OS is do your homework. Make sure you have all the drivers for your hardware before taking the plunge.

 

XP Pro x64 was before its time. Vista x64 is 64 bit computing done right. It is an excellent choice of OS if you want to go the 64 bit route. You won't have to replace anything unless its old or an odd ball item.

 

Actually, the market isn't pushing 64-bit, consumers are, but that's a different story.

Vista x64, from what I've heard (I plan to install it over my existing x86 over the summer) has been extremely stable and has performed well without issues. As long as your peripherals aren't ancient and are made by a company that still provides support for its products, chances are they have a 64-bit driver out by now, but make sure you check beforehand.

As stated, 64-bit can run 32-bit programs just fine. If you want/need >= 4 GB RAM, then I suggest you don't hesitate to go for Vista x64. There are many people here who are willing to help if you run in to issues: http://forum.notebookreview.com/showthread.php?t=186030

 

i installed it... and the truth is..

nothing actually takes its advantage EXCEPT for videogames. But its prety backwards compatible. and it installs all the 32bit stuff in a seperate Programs Folder, which is prety interesting.

I personally had huge headaches installing it on my Sony Vaio.. and i don't recommend it for Vaio owners. But finally i got it working just today actually and iam prety happy with it... but its just sad how much stuff is actually coded for 64 bit (barely anything...)

 

Cause people want their 0.5 GB of memory darn it!!!!!

With SP1, Windows lists the actual amount of memory installed, not what it can use.

Ever since this change, I haven't noticed any threads titled "OMGWINDOWSCANTUSAALLMYMEMORY" or any titled "OMGWHEREDIDALLMYMEMORYGO"

 

These questions get asked way too much, seeing as google.com has been around for 10 years. You can easily google this and get answers. You can even read a whole wikipedia article about the x64 architecture.
